Remember how Captain America's shield made a little cameo in Iron Man 2? Well, that little in-joke was just a taste of things to come. It's now confirmed that Howard Stark, Tony's father, will be in next summer's Captain America and will be played by Dominic West.
We saw plenty of Howard Stark in Iron Man 2, where he haunted Tony with his negative fathering via old newsreel footage, where he was something of a Walt Disney type and was played by John Slattery. Since Captain America takes place during World War II, the significantly younger Cooper will fill the role, where he'll presumably have a hand in transforming Steve Rogers (Chris Evans) into a Nazi punching star spangled avenger.
