i like sean astin and vinnie jones but they could not save this film . there be little if any explanation a to how the time travel device work and the actor just throw out the term string theory and worm hole . astin say he shave a rat and send it back and it come back harry . who the hell do he send it back to and himself who do not know the rat be shave . the dialog be write for a comic book and there be so many small logic mistake it really distract from the story . there be also this spin camera effect use during the gun fight and in the bus bathroom which be nothing more than distract . i hope sean astin doesn not become the next star to finish one of the best movie of all time ( lotr ) only to end up make crappy b movie like this one .
