The Land Before Time (partially found deleted scenes of animated film; 1988)
Don Bluth's 1988 animated feature film The Land Before Time, was originally to have a running length of 79 minutes, but was cut down to 69 minutes, due to the removal of various scenes that were deemed either too frightening or too difficult for children to understand (plus a few other minor cuts). A total of 19 scenes were cut from the film before release (against Bluth's wishes), namely scenes in which potentially overwhelming images from the fight with Sharptooth (the Tyrannosaurus rex) were shown, including a scene of Sharptooth landing on Littlefoot's mother (which was altered to show the event only in shadow). Allegedly, some early VHS copies contain the original aforementioned scene in which Sharptooth lands on Littlefoot's mother (although this has not been confirmed).
In addition to these scenes, the ending was also altered. Originally, Littlefoot was to find the Great Valley on his own after parting with his friends, before returning to his friends and helping them defeat Sharptooth, later entering the Valley with his reunited group. Other scenes cut from the film included one in which Ducky is seen taunting Sharptooth by making faces at him, and one that shows the inclusion of Spike into the gang and the decision to lead him using berries. The rumored scene in which the main characters come upon an oasis inhabited by "crown-heads" (Pachycephalosaurus) and "gray-noses" (Saurolophus), who refuse to share food and water with one another, giving Cera an epiphany on not judging others based on their species was rumored to be part of the film, but was never actually animated.
The original cut of The Land Before Time has never shown up in any form of public release, and it is largely believed that the extra footage has been either lost or destroyed. Despite this, stills from some of the deleted scenes have shown up in the past, some, interestingly enough, in the movie's counterpart storybooks Friends in Need, The Search for the Great Valley, and The Land Before Time: The Illustrated Story. Small snippets from some of the deleted scenes can also be found in pieces of promotional material for the movie that came out before its release. It is rumored that an unedited copy of the film was accidentally sent to a Finnish broadcasting company, which they then subsequently aired, although this claim has never been verified.
