Tom Sawyer has just one shot in this version of the film where he yells "Go for the glory!", even though he is a major character in Mark Twain's book. The actor who says "Go for the glory, Huck!" at 03:43 on the DVD is Danny Tamberelli who is listed in the end credits as playing "Ben Rodgers". At 03:45, another boy says "Ya, go for the glory", but Tom Sawyer, who has a large roll in the ending of the book that is not in the film, does not appear in the end credits.
