Scott plays Bernardito, a member of the Mambo Kings Band.  While he only has lines in one scene (approx. 52 minutes into the movie), he can be found in any scene that the band plays in (playing the saxophone) and he also appears in various other scenes such as the wedding reception and sitting on the couch watching their band leaders appearence on the "I Love Lucy" show.  The movie itself is about the two band leaders who are also brothers and their struggle in the US after they leave their homeland in Cuba.  The movie itself was pretty good in my opinion and with Scott as an added bonus you can't go wrong with this one, especially if you like this kind of music.
