Warning: This article contains some major spoilers for the ending of Fast X.

Fast X is one of the most expensive movies of all time, and it's certainly got a cast large enough to match its massive budget. But for director Louis Leterrier, who took over behind the camera a week into production after franchise stalwart Justin Lin quit, the cast wasn't quite big enough.

The issue, as far as Leterrier was concerned, wasn't about how many people they had in the Fast & Furious #family, but rather who was missing from it.
