Disney's Anne Frank/WMG

This Movie is real... But not in this universe
The movie came from an alternate dimension where Disney was attempting to do Oscar Bait but the project had its budget cut and Disney was made to censor and Bowdlerize what was previously a straight adaptation of the The Diary of Anne Frank (it was around the time they were doing The Black Cauldron and they didn't realize that flopped until they were well into production). Due to the fact that the voice acting was already done when the budget was slashed this led to a cast far more notable than the movie would warrant. The Nostalgia Chick got her copy of the movie from Dr. Linksano in a Secret Santa exchange.

Anne owes her happy ending to Kyubey from Puella Magi Madoka Magica.
Kyubey used his power to grant Anne's Wish "I wish that no harm will come to my family and I". This fits Disney's wish motif appropriately but it's twisted leading to her real life tragedy. Being worked to death did not qualify as "harm" under her wish so she was worked to death in Auschwitz becoming a witch thus leaving no body in the death camp.

Pocahontas was severely retooled after Anne Frank tanked.
The poster states "From the makers of Pocahontas", which would not be released until 1995, even though Anne Frank was released in 1989. Presumably a Pocahontas movie was to be released at about the same time, or even before Anne Frank premiered, but once the backlash against Anne Frank reached epic proportions, the Pocahontas movie was delayed and reworked to the point that it took over six years before Disney deemed it acceptable enough for theatrical release.

Ludvig and Olga are related somehow.
When one of the camp prisoners cries "I Have a Family," Olga mockingly comments "Oh, I used to have one too...until they got in my way." Given that we know that she also killed, the latter of whom sort of looks like her...
