In addition to these two big names, Lewis Pullman, an up and coming actor, and the son of actor Bill Pullman, has also joined the cast.
The cast of the upcoming Top Gun sequel has been growing fast, but the long-awaited project just added even more names, including a couple of potentially big ones.
Mad Men star Jon Hamm has come on board the film, as has Academy Award nominee Ed Harris.
While neither role has been revealed, names like this don’t tend to be added for small, unimportant parts.
