When discussing reused animation in cartoons, I have found that there are two types.

One is the one where the drawings are used exactly as they appeared in another cartoon, or even the same one (ex. a scene of skeletons dancing from The Skeleton Dance were reused in Haunted House).

The other is the kind where the original animation was the basis for "new" ones; what I mean is that the new animation could be the same character wearing a different outfit, or a whole new character altogether.

You get the picture?

Being, I'm currently going thru Tom And Jerry, here is a few examples of remakes,

The Egg And Jerry (1956) *2 *6 (Remake of)

Hatch Up Your Troubles (1949)

Has different backgrounds, but animation is consistant

Tops With Pops (1957) *2 *6 (Remake of)

Love That Pup (1949)

Has different backgrounds, but animation is consistant

Feedin' The Kiddie (1957) *2 *6 (Remake of)

The Little Orphan (1949) *0 (Cameo)

Has different backgrounds, but animation is consistant, other than

Scene of Jerry looking in cupboards for food
Scene of Mammy Two Shoes entirely

You may want to ponder a 3rd type, I call them Compilation, they reuse clips with new linking animation (i.e. bridging sequences between clips) here is a few examples,

Jerry's Diary (1949) *5 (Contains clips from)

Tee For Two (1945)
Mouse Trouble (1944)
Solid Serenade (1946)
The Yankee Doodle Mouse (1943)

Smitten Kitten (1952) *5 (Contains clips from)

Salt Water Tabby (1947)
The Mouse Comes To Dinner (1945) *0
Texas Tom (1950)
Solid Serenade (1946)

Life With Tom (1953) *5 (Contains clips from)

Cat Fishin' (1947)
The Little Orphan (1949) *0 (Cameo)
Kitty Foiled (1948)

Might thinks of a 4th, here is some examples of the Academy/CinemaScope versions,

Pet Peeve (1954) *1 Academy/CinemaScope/Fullscreen

No different backgrounds between Academy/CinemaScope/Fullscreen and animation is consistent

Southbound Duckling (1955) *1 Academy/CinemaScope/Fullscreen

No different backgrounds between Academy/CinemaScope/Fullscreen and animation is consistent

Here's the difference,

Academy contains more top and bottom of the viewable frame than CinemaScope
CinemaScope contains more left and right of the viewable frame than Academy

Fullscreen contains less left, right, top and bottom of the viewable frame than Academy
Resulting in an insignificant loss of the left, right, top and bottom of the viewable frame

Fullscreen contains less left and right of the viewable frame than CinemaScope
Resulting in a significant loss of the left and right of the viewable frame

Note: Fullscreen is not an official film format, it is the use of pan and scan to adjust the ratio to 1.33:1, to fit the older TV standard of 4:3. Used mostly for release to TV and video.

Being we are on this subject, here is a point to ponder. Information on the Tom And Jerry releases I find is, they released 4 in the Academy/CinemaScope ratio. I have already provided info on 2,


Touche, Pussy Cat! (1954) *1 Academy/CinemaScope/Fullscreen

(Muted) Nibbles @ 4:40 Singing "Frere Jacques" Uses an unreleased stereo mix of the soundtrack

To my knowledge there is no known official release of the CinemaScope version without the edited scene.

No different backgrounds between Academy/CinemaScope/Fullscreen and animation is consistent


Pup On A Picnic (1955) *1 Academy/CinemaScope/Fullscreen

No known official release in CinemaScope
Academy ratio matted to appear in widescreen ratio of 1.85:1
Using hard-matte to adjust Academy Ratio to 1.85:1
Resulting in a significant loss of the top and bottom of the viewable frame

Has different backgrounds between Academy/_/Fullscreen, but animation is consistent

Well I noticed that Betty Boop was really bad with this, as every episode re-used that grandpa thinking scene.
