Re: Jeremy Renner is Hawkeye! - Part 1
Marvel movie universe has this whole James Bond/Patriot Games Espionage world they could explore with characters like Hawkeye and Black Widow. The Hawkeye comics showed (with the Tape storyline) a small part of that world they could use. Hawkeye, Black Widow, Young Nick Fury: Agent of SHIELD (a prequel or sorts that fills in gaps between Cap 1 and Iron Man 1), SHIELD TV show, Winter Soldier, and Spider-Woman (triple agent working for shield against Hydra for Hydra agents shield for shield).
They have this whole world of SHIELD and agents and assassins and secret agencies and terrorists and super powered agents they could delve into. A world kept secret from even Thor and Iron Man.
