Watch Loves Labor Won (1948) Official Trailer

Many sight gags find their way into this story of Mighty Mouse coming to the rescue of a fair maiden. Oil Can Harry is determined to marry Pearl Pureheart. Mighty Mouse can't stop him because he is tied in front of a big cannon. Pearl manages to escape from Oil Can Harry, singing opera all the while. This cartoon is played like a chapter from a cliffhanger serial, with lots of action and suspense (and singing).
