Looney Tunes and Merrie Melodies filmography (1940–49)

This is a listing of all the animated shorts released by Warner Bros. under the Looney Tunes and Merrie Melodies banners between 1940 and 1949.

A total of 307 shorts were released during the 1940s.

1942
This year marks the beginning of production of color Looney Tunes. For this year and next, most would still be in black and white. Looney Tunes also adapts the "target" titles similar to Merrie Melodies, usually with thicker rings.

1943
Blue Ribbon re-releases start this year, where from cartoons released in the 1935–1948 season have their original credits cut.

1944
Leon Schlesinger sold his cartoon studio to Warner Bros. in 1944; Eddie Selzer took over as producer after Buckaroo Bugs was released.

Beginning this year, all cartoons are in color. Some cartoons would be produced in two-strip Cinecolor in the 1947–1949 season, to save money. All cartoons would be produced in three-strip Technicolor by 1950.

1945
Every non-Bugs Bunny cartoon released this year except for Draftee Daffy, Behind the Meatball, A Gruesome Twosome, Wagon Heels, and Nasty Quacks were given Blue Ribbon reissues. Starting with Ain't That Ducky (which was later reissued), the opening version of The Merry-Go-Round Broke Down is shortened. Starting from Hare Trigger, the opening version of Merrily We Roll Along is also shortened. However, Warner Bros. kept the long version of the Merrily We Roll Along for a.a.p. Blue Ribbon reissues until 1956.

1946
The Looney Tunes series begins using "That's all Folks!" ending sequences, similar to Merrie Melodies (starting with Kitty Kornered, on that cartoon the Merrie Melodies ending theme is heard).

1947
Every non-Bugs Bunny cartoon released this year (as well as any cartoon in the 1946–1947 production season) except for A Pest in the House, Catch as Cats Can, and Mexican Joyride, were given Blue Ribbon reissue. All cartoons are in 3-strip Technicolor, except where noted.

1948
All cartoons are in 3-strip Technicolor, except where noted.

1949
All cartoons are in 3-strip Technicolor, except where noted.
