You mean like Stallone, Arnie, Willis (to an extent)...
It's a shame these casts weren't brought together 20 years ago, would have been even more epic than now.
How about Samuel L Jackson and Harrison Ford, and yep Chan and maybe the guy from Hot Shots (if he's not on his drug bender). Also Segal would be a possibility.
All so old though!
Arnie in Sly are in their mid 60s. Willis is in his mid 50s. With the exception of Arnie they're still in relatively decent career and physical shape.
The Chuck Norris meme really did more PR for him than anything he's done in twenty years. Guy's well past it and has been for a while.
