I just watched it and thought it was it at first but im pretty sure one of the last scenes in the movie was jumping a bridge with a dump truck or some type of big rig. Im not sure he was working on a video game, maybe he was just trying to figure out the math of the jump. Thanks
I think I vaguely recall the film you're talking about. But, I can't really give any more details. So, just chiming in to tell you you're not crazy or misremembering too much.
