Visible crew/equipment: When Chuckie and his friends show to Will his new car towards the end of the movie, a boom microphone is reflected on the rear window and also on the rearview mirror's steel cladding moving backwards when Matt Damon steps on forward.
Visible crew/equipment: When Will has his last therapy session with Sean, he reaches up to hug Sean. His shirt in the back rises up, and you can briefly see some sort of small black equipment/cables that look like a battery or mic pack tucked into the back of his pants.
Suggested correction: Patently false. His shirt does not lift up during this scene. Only his pants, belt, and shirt are visible on his back side. However, the shirt and pants are somewhat crumpled, possibly giving this illusion.
