I was thinking of a few other movies I remember seeing or hearing about that have had extended TV cuts, sorry if these have been brought up before.

Airplane! (Although it appears most if not all of the scenes are on the latest DVD release)
Airplane II
Coneheads
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.
