Iron Man

It is tough for me to imagine Robert Downey Jr. as Tony Stark (Iron Man).

It is tough for me to imagine O.J. Simpson as human too. (That may be in another post.)

He has the old comic book Tony Stark look so it maybe a go.

Samuel L. Jackson should make one kick-ass Nick Fury too.

• Robert Downey Jr. as IronMan?

• Terrence Howard as Jim Rhodes.
  
• Samuel L. Jackson as Nick Fury?
• Jeff Bridges as Obidiah Stane.
