This may be a spoiler to some people, so highlight to read:

In Attack of the Clones, there's a scene that takes place right after Jango Fett and Obi-Wan battle. As Slave I takes off with Boba Fett at the controls, Jango Fett walks up the ramp and into the ship as the doors close. Just before he gets in, he hits his helmet in the doorway.

I thought I imagined this happened, but another reader said he saw it too. Is this a tip of the helmet to the stormtrooper that hit his head in A New Hope? If so...cool!
