- Airplane! (Although it appears most if not all of the scenes are on the latest DVD release)
- Airplane II
- Fast Times at Ridgemont High
- Gremlins (I believe only one new scene was added to some TV broadcasts)
Are any of these currently being worked on?
P.S. I also heard there's a DVD version of Dumb and Dumber that includes a deleted scene of Lloyd returning to the little old lady after getting change and she's gone.
