The weekend after “Iron Man” opened, people everywhere were buzzing about the secret scene after the end 
credits with Samuel L. Jackson in a cameo as Marvel Comics’ Nick Fury. It was so successful, actually, that a subsequent scene Robert Downey Jr. filmed to go at the tail end of “The Incredible Hulk” was moved up to the last scene in the film and featured in TV commercials.
But what escaped most viewers’ notice were hints in both movies signaling the forthcoming appearance of another Marvel icon: Captain America. With “Iron Man” out on DVD now, and “The Incredible Hulk” hitting shelves next Tuesday, sharp-eyed fans can catch tiny glimpses of Cap if they know where to look.
A few perceptive observers noticed during the theatrical run of “Iron Man” that in the scene where Pepper Potts (Gwyneth Paltrow) walks in on Tony Stark (Robert Downey Jr.) as his armor is being removed, there was something on the workbench behind him. Circular, with red and white stripes and a half-completed star in the center, it was speculated that this was Captain America’s iconic shield.
