This may come as a surprise to many; I didnt realize that Union Jack was in Captain America until after II had seen the film. While Im aware of the character and a lot of his history, I had forgotten what his real name was. In retrospect it was a little weird to feature Caps British counter-part in the film, but not really. Another one of those, who is this for? moments in comic book movies. James Montgomery Falsworth is a member of the Howling Commandos in the Cap film, and aside from being British in the film, there isnt any reference to him being anything more than a soldier. However, like the Howling Commandos idea, there is still a war to fight at the end of First Avenger. Steves death leaves a void, and a new icon must be created to keep moral up. Enter Falsworth as Union Jack, a hero that wears a costume that is similar to Caps in the patriotic sense. Union Jack can contend with the remnants of The Red Skulls forces and face a new foe that seeks to replace Skull in the Nazi hierarchy, Baron Zemo! Zemo is attempting to carry on The Skulls work and win the war for the Nazis, thankfully Union Jack is also carrying on a legacy. In the final stages, both Zemo and Jack are subjected to something that will change history forever. This would be an excellent way to introduce the Infinity Formula as an attempt to recreate the Super Soldier Serum (Steroids that are on steroids). This puts the Howling Commandos and Union Jack in play for future films told in modern times.
