(at around 37 mins) Hayley Atwell (Peggy Carter) surprisingly touching Chris Evans' chest, as he emerged from the pod upon turning into Captain America, was very much improvised, and the surprise on her face is genuine, as she admitted in interviews she was very taken by Chris' physique and nearly broke character and ruined the take that made it into the film as a result.

(at around 42 mins) When Steve Rogers pulls Heinz out of his little submarine boat and throws him onto the dock - then climbing a ladder out of the water himself - both characters are dry. Their clothes are dry and no water is dripping on the ground beneath them.

There is a statement at the end of the closing credits: "Captain America will return in The Avengers". After that, a trailer for The Avengers (2012) is shown.

The version of the film shows in AMC Theaters as part of a pre-Avengers Marvel Phase One marathon features an exclusive intro from Agent Coulson, talking about the film and the character. These Coulson intros were later includes as bonuses in the Avengers Phase One box set.
