Previously known as "Techniscope"
THX 1138 was shot in Techniscope.
Natively 2.35:1 aspect ratio
Uses half as much film as 4-perf
Is difficult to find cameras and telecine facilities
The cut for 4:3 TV is radical because there's no top and bottom to expand into
The new, fine-grained stocks make 2-perf very attractive
Be very careful about hairs in the gate and lens flare because there's almost no frame line
Tough to optically print but it can be done (e.g. Multivision235)
