Obscure Media: Encore VFX Article

Brought to us courtesy of @widowswinter, who's been working hard to dredge up these gems from the past.

We've all seen this cover by now, but in case you didn't know, Encore was an Australian film trade magazine. It switched to an online format and then seems to have ceased publication around 2013. Some of their articles can be found at https://mumbrella.com.au/, but none going back to 2006. Widowswinter accessed this article via the National Library of Australia, which houses physical copies of the magazine and will make copies/scans of some of their collection.

ENCORE I 22 I V24 ISSUE 2, FEBRUARY, 2006

Digital effects were integral to writer/director Gregory Read's Like Minds, the UK/Australian psychological thriller starring Toni Collette, Richard Roxburgh, Eddie Redmayne and Tom Sturridge.  

With production split evenly between Australia and England, where the story is set, the dual role of the DFX was to heighten the in camera drama, and to solve problems created by on-set limitations and impracticalities. This was especially true for the film's opening train sequence during which schoolboys hang outside the door of a train travelling at 80 km/h, playing 'chicken' with the rapidly advancing stanchions (posts that support the overhead electric wires).

"Even if we could shoot the whole scene on a live train travelling at speed, getting the angles in and out of the train with the presence of real stanchions isn't realistic, not to mention the danger of attempting such a live sequence," said Read, who consulted with DOP Nigel Bluck and VFX supervisor Dave Morley, of Sydney-based VFX house Fuel International, to determine the best way to shoot this scene. "The upshot was to have two shoots; the first being the boys on a live train minus stanchions, travelling at its top speed of 20km/h. We used a wind cannon and lighting rig to emulate speed. The boys were cabled into the train, which gave them the opportunity to hang out, feel the 'rush' and give me the performance I wanted . The rest of the scene was shot in a shed with two very big guys rocking the train."

Like Minds features Collette in the role of a forensic psychologist appointed by police to determine whether there's enough evidence to lay murder charges against 17-year old Alex (Redmayne), accused in the shotgun death of his schoolmate Nigel (Sturridge).

The train scenes were initially earmarked to be shot in Adelaide but the unavailability of a suitable 1970s-style electric train meant the production shifted to a train museum located in Cessnock, NSW. Fresh stumbling blocks at the new location included a train carriage without a front engine and the absence of on location electricity; factors which necessitated the deployment of a bright yellow ex-BHP locomotive to propel the 'electric' carriage backwards and forwards at a maximum travelling speed of just 20km/h.

Fuel's task included the creation of the CG stanchions, which Read wanted to "crash into frame very close to the carriage then vanish into shadow".

"The shot required the stanchion to race towards the boys, barely missing one of them. However, when the stanchion was put in it just didn't look right so David [Morley] gradually scaled up the stanchion to 300 percent as it raced towards us so that it worked, visually and dynamically. As an added effect, when this stanchion slams past it actually hits the camera on which David introduced shudder."

Morley's team rigged up a series of par cans (stage lights) attached to a programmable lighting desk that enabled them to set the speed of lights turning on and off in series to simulate the feel of the stanchions travelling past the carriage at the desired speed of 80 km/h.

"Each of the CG stanchions has its own light pointing down towards the train and we used the par cans to give us the motion of the light travelling past," Morley said. "We built CG stanchions to match the style of what they have over in England, and from reference gathered off the web and footage Greg shot in England, then tracked them in and composited them all together."

When working on shots looking down the length of the train, the ground plane was sped up 400 percent. This was done to disguise the fact that the train was actually only travelling at 20 km/h.

"That would get put back in and then we'd have the CG stanchions over the top of that," said Morley. 'There was normally only one extra carriage behind the one that we were working on, so we ended up having to extend extra carriages as well. Because we only had one train rigged with the lights we ended up shifting the camera up one carriage length then duplicating this carriage for the two missing carriages."

The variance in visible rainfall during the Cessnock shoot presented another problem to be solved.  

"We'd set up to get the master shot, which was a very large crane shot moving down onto the railway tracks from about 30 feet up," Read explained. "In this environment we had two large rain towers with rotating heads which produced heavy rainfall, however when we swung  around to shoot reverse shots there was very little backlight and the rainfall was barely visible. We knew we didn't have time to move lights - let alone the travelling train in the background where the lights would need to stand. It was a matter of placing CG rain into the background of those shots so they matched the master."

Like Minds is set in the middle of the English winter. Obviously, Cessnock's 45-degree temperatures created obstacles. Among the challenges were short night shoot hours, actors having to wear heavy fur-lined clothing and the need to frame out all 'summer' foliage - especially gum trees.

In addition, while the English shoot took place in wintertime, Read was keen to include a shot of the school location in summertime. Fuel was called upon to make shots filmed in winter appear as though it was summer. This was done with sky replacements, adding leaves to trees and replacing snow with grass. Among these was an interior shot of the exterior through a window.

Fuel worked on 89 shots in total including the opening title sequence, which sees a camera move along a darkened surface before rising to show raindrops falling on this surface, which is revealed to be a train track.

"Suddenly a train rushes over the track and we cut out to a wide shot and there's the boy hanging out of the train," said Read. "I thought we could use a motion control rig and then put in the CG later but then practicality and cost came into it and I faced with the reality that this shot was too much of an indulgence; we didn't have the budget and so I turned to David and said 'Help! This is the shot I want to do'.

Armed with Read's storyboards and a second unit, Morley directed the title sequence himself, opting to use a live train to give it authenticity.

"We had to carefully choreograph the timing of both the camera tracking back and the train barrelling down the track straight for us with quite a few dry runs separately with both train and crew until we were confident we had the positions the camera needed to be in relation to the train," explained Morley.  "We still had several safety people standing by to quickly rip crew out of the way of the impending train if they had not reached the agreed ‘point of no return'  position. In the end we got exactly what we wanted."

Once the shot had been captured, Fuel scanned the image at 4K, smoothed the camera move and retimed the sequence. In addition to the titles CG sparks were added to the undercarriage as the train passed by.
