Aleksei Mitrofanov of the Liberal Democratic Party (LDPR) told Georgian reporters he now believes the controversial film was "a political mistake."
The two leading roles in the 30-minute film, "Yulya," resemble Saakashvili and Tymoshenko. It ends with a sex scene in a helicopter.
Mitrofanov said the film had had "an impact quite different from what I expected."
Both the Georgian and Ukrainian governments ignored the movie.
