Robert De Niro compared Donald Trump to Travis Bickle, the mentally disturbed character he played in the 1976 movie “Taxi Driver.”

“What he has been saying is totally crazy, ridiculous, stuff that shouldn’t be even… he is totally nuts,” De Niro said.

His comments came during a Q&A at the Sarajevo Film Festival on Friday, according to the AP.

Elaborating on the character which earned the actor an Oscar nomination, De Niro said, “One of the things to me was just the irony at the end, [Bickle] is back driving a cab, celebrated, which is kind of relevant in some way today too.”

He then drew a comparison to the current presidential candidate for the Republican party: “People like Donald Trump who shouldn’t be where he is so… God help us.” The AP reports that De Niro’s comments were met with applause.

De Niro added during the Q&A that he thinks the media has focused too much attention on Donald Trump. But he has seen a shift in tone that now resembles, “Come on Donald, this is ridiculous, this is nuts, this is insane.”

The actor was attending the film festival, now in its 22nd year, to receive its first ever lifetime achievement award.
