Thor Easter Egg - Hawkeye in Thor

During the scene when Thor is trying to reach his hammer in the SHIELD compound, an agent is sent to take him out and starts to reach for a gun, but chooses a bow instead. This character is then lifted into the air to shoot from above. The character is addressed by agent Coulson as Barton. Clive Barton is also known as Hawkeye in the Avengers comics and was played in the movie by Jeremy Renner, who was uncredited in the movie but is also playing Hawkeye in the Avengers movie coming out this summer.
