t.A.T.u. Paragate was an anime movie set to be released in 2004 based off the at-the-time popular pop group t.A.T.u. It was announced in 2003 and was to be animated by iMOVE (who did animation work on Death Note and Inuyasha among other popular 2000's anime).
However, in early 2004 the girls of t.A.T.u. broke their contract with their manager Ivan Shapovalov, who confessed to basing the act's duo off of child pornography sites. Along with the contract split, the movie ended up being shelved and its website was deleted in 2005.
The girls of t.A.T.u. split in 2011, saying they were "very tired of each other", making it very unlikely the film will ever be released.
