The story for Back to School is essentially the same thing as Life of the Party and College Mom, with Melissa McCarthy playing a female version of Rodney Dangerfield.
Eva Kowalski also claims that Melissa McCarthy knew about College Mom the whole time and willingly put her own name on the script.
Melissa McCarthy and Warner Bros. are being sued for alleged copyright infringement over the story for Life of the Party.
Life of the Party made just over $65 million globally and Eva Kowalski is seeking $10 million in damages.
