Leading man
It's time for Hollywood to start casting more leading men like Oscar Isaac. He reminds me of Harrison Ford in his quiet intensity. He's handsome but not in a loathesome male-model way (can't stand Ed Skrein or Sam Caflin's face. I'm sure they're nice people but their faces look so smug it's unbearable to watch for 90 minutes). Another reason he reminds me of Harrison Ford is the way he holds the screen; I can see him in an Indiana Jones or Han Solo-type role and I believe he'd be perfect for those kind of roles.
Say they reboot Indiana Jones (please don't); I think Oscar would be perfect for the role. Chris Pratt (who's very good) as well but that's another discussion on another message board.
I remember seeing him in Robin Hood and I couldn't stand him. Plus I wasn't convinced he looked.. English enough (unless that was a conscious decision.. I dunno) to play the role he played. However, in Robin Hood he played the role very well and was convincing in his portrayal of the character. Since then, he's appeared as a supporting actor in many films I like such as Drive and now I'm convinced he should be cast more as a leading actor in films.
