Dustin Hoffman has agreed to appear in the third instalment of the Meet the Fockers franchise which has already been filmed, reports say.
The 73-year-old was written out of Little Fockers after movie bosses failed to reach a deal with him, according to Deadline Hollywood.
But after director Jay Roach convinced the star to reconsider, Hoffman's character was written back in.
He is expected to film his scenes in a series of re-shoots next month.
Hoffman will reprise his role as Bernie Focker, the on-screen father to Ben Stiller, who is now coping with parenthood.
Barbra Streisand is returning as Hoffman's on-screen wife.
A Universal Studios insider told Deadline Hollywood the part was similar to the one offered to Hoffman in the first place.
The source added the film, which is due to be released in December, could have been released in its current form, but the studio "want to make it better - it's an investment in the future of the franchise".
Stiller, Robert De Niro, Teri Polo, Blythe Danner and Owen Wilson will also reprise their roles in the film.
The first two films in the franchise, Meet the Parents and Meet the Fockers, took more than $445m (£289m) at the the US box office.
