In light of the other thread about remade movies, I thought we might talk about movies that should be remade, and how you would cast them.
There is no restriction on actor's budget, just cast who you think would be best.
I will start.

Although the original is a very gay favourite, it is seriously flawed in many ways.
I would tighten up the story by explaining the gay adoption bit a lot more clearly, and showing the relationship between the Arnold and Alan characters a lot more intensely.

Arnold Beckoff: Jeremy Sisto
Ma Beckoff: Candice Bergen
Ed: Jonny Lee Miller
Alan: Freddie Rodriquez
Laurel: Michelle Williams
David: Angus T. Jones
