Alvin and the chipmunks go to the movies: back to alvin's future (1992)

Imagine being able to just zip back and forth in time, whenever you feel like it! Well, that's just what The Chipmunks do in this time-travel misadventure, Back to Alvin's Future! Buckle up for lots of excitement, music and laughter as eccentric Prof. Clyde Crashcup whisks the Chipmunks back in time to the year 1957, just as Alvin of the Past is going to give up everything and quit playing music forever. Alvin of the Present has his work cut out for him, because if he doesn't convince Alvin of the Past that the rewards are worth all the hard work, there won't be any Alvin of the Future, or Theodore, or Simon ... in fact, no Chipmunks!
