Answer
What is the best AI tool for making a full AI movie?
Nothing generates a feature. What exists is tooling that holds continuity across many shots so a feature can be assembled — and the honest state of the art.
Nothing currently generates a feature-length film, and any tool implying otherwise is describing an assembly pipeline. The realistic state of the art is planned, chained shooting: a brief becomes a shot list, each shot is a short generation conditioned on the previous one's final frame, and the shots are joined. Unlimited Studio does that up to 30 minutes per run, with longer work made by starting a new film from the previous one's closing frame so cast and location carry across. For a true feature, expect to work in acts of that length, to budget seriously — about 28.7 credits per second of finished film — and to accept that the longest single film completed here so far is ten shots, so a feature is an unproven extrapolation rather than a solved workflow.

Why 'AI movie' is mostly a workflow claim
Per-clip ceilings are measured in seconds. Every minute of finished film is therefore dozens of generations, and every product that advertises long-form output is choosing how to hide that fact. The ones worth using hide it by holding continuity; the ones that are not simply concatenate.
Judging a long-form tool means judging the joins, not the clips.

What a workable long-form pipeline needs
A planning stage that writes every shot in one pass, so the ending exists before the shooting starts and the film does not wander. A locked cast and set of locations carried into every shot. Frame chaining, so each shot continues the last. Assembly into a single file with a caption track. And a failure model where one bad shot does not destroy the run.
Those five together are the difference between a film and a folder of clips.
Detail
Budget honestly before you start
At roughly 28.7 credits per second, a 30-minute act is near 51,660 credits. A ninety-minute feature is three times that again, several times over, and that arithmetic is worth doing before writing the script rather than after.
Failed generations are refunded automatically, so the spend tracks footage actually delivered — but the total is real, and it is the reason most AI long-form work sensibly stops at short-film length today.
