I uploaded on Youtube a scenemaker from Terminator : The Sarah Connor Chronicles.
Interview of the director of s01ep03 of Terminator : The Sarah Connor Chronicles "The Mousetrap", as well as actors Thomas Dekker and Garret Dillahunt on the making of the scene where John and Cromartie jump into the Pacific ocean at Santa Monica Pier.
Summer appears shortly at the end of the clip. A angry Cameron says to John : "I don't swim!".
