Ray Liotta is supposed to be 21 early on.....poor guy already looks 50 in that movie
He doesn't look that old. lol And I don't think it would have worked as well having a teenager version, another actor playing a 20-something version, and a 40+ version using Ray. At least they did a good job as the coked out, old version of him. He looked much different than the 20-something version.
I think if anything Joe Pesci looked older than a 20-something. lol
It could be worse, it could have been all CGI to make them look 21. We know how that would have looked back then. hahaha
