i didnt catch tha backpack either however i did liuke the movie!

that part was when he broke into the mansion and was under ground ... also seen prior to that as he climbed the mountain to sneek in.

at the start , you will spot a lot of X-treme athletes, both BMX and FMX, the dive with the corvette was by far the best part of the movie, Didn't see the icon backpack . have to watch it again
( Tony Hawk even had some lines in the movie )
