The Tree of Life trailer

After nearly thirty years away from Hollywood, famed special effects supervisor Douglas Trumbull contributed to the visual effects work on The Tree of Life. Malick, a friend of Trumbull, approached him about the effects work and mentioned that he did not like the look of computer-generated imagery. Trumbull asked Malick, "Why not do it the old way? The way we did it in 2001?"[22] Working with visual effects supervisor Dan Glass, Trumbull used a variety of materials for the creation of the universe sequence. "We worked with chemicals, paint, fluorescent dyes, smoke, liquids, CO2, flares, spin dishes, fluid dynamics, lighting and high speed photography to see how effective they might be," said Trumbull. "It was a free-wheeling opportunity to explore, something that I have found extraordinarily hard to get in the movie business. Terry didn't have any preconceived ideas of what something should look like. We did things like pour milk through a funnel into a narrow trough and shoot it with a high-speed camera and folded lens, lighting it carefully and using a frame rate that would give the right kind of flow characteristics to look cosmic, galactic, huge and epic."[23] The team also included Double Negative in London, under the supervision of Paul Riddle, who handled the astrophysical aspects of the segment. Fluid-based effects were developed by Peter and Chris Parks, who had previously worked on similar effects for The Fountain.
