When Cody Banks crashes a rocket propelled snowboard into a tree, Ronica Miles meets him using a jet pack. When she lands, she unbuckles herself and all the straps are seen free. After a shot of Cody's snowboard in the tree, it goes back to Ronica and she begins unbuckling herself from the jet pack again.
At the end of the movie, when Cody and his girlfriend sit on the car at the beach he is called by the CIA. Listen to the ringtone of the cellphone - it's the same as from the "Our Man Flint" series, perhaps best known now for being used in the Austin Powers movies.
