One of my favorite details of this movie is that the semi-antagonistic ENCOM executive Dillinger uses emacs [0], while Flynn uses vi. Clearly, the VFX artist who made the film's UNIX shells had a preference!
(Dillinger is also shown running "ENCOM Linux" -- is the VFX artist a BSD user? As he cycles through his buffers, we see a split second of `hanoi-unix`; definitely not the type to pay attention during boring board meetings!)
