Loopy De Loop is the first theatrical cartoon series produced by Bill Hanna and Joe Barbera after leaving MGM and opening their new Hanna-Barbera Studios.
The first of 48 Loopy shorts which spanned from 1959 to 1965.
This was the first of only two Loopy shorts to have the original theme music before switching to a more familiar one.
The first Hanna-Barbera theatrical cartoon distributed by Columbia Pictures after working on television animation since 1957 from Screen Gems after MGM's original animation studio was shut down, while its predecessor UPA losing its deal with the studio in 1959 due to budget problems until Sony bought the animated theatrical shorts for the animation studio. Ironically, it was owned by Warner Bros. which brought us Looney Tunes and the Tom and Jerry theatrical shorts.
The first theatrical short directed by William Hanna and Joseph Barbera after MGM's animation studio closed down in 1957 and opening their new Hanna-Barbera animation studios.
