Movie director Joss Whedon compared Ivanka Trump to a dog in a tweet he sent Tuesday.

Whedon, who directed the Avengers and identifies as a feminist, sent a tweet with a picture of Ivanka's husband, Jared Kushner, watching President Donald Trump signing documents.

"Hey, keep your eyes on this fucking prize too," Whedon wrote. "He's a Voldemort in training, & unlike the Pekingese he married under, can play the long game."

The message drew sharp criticism on Twitter for comparing Ivanka to a Pekingese, a dog breed. Breitbart highlighted a number of the responses sent to Whedon calling him out.

@joss The left used to be better than this. You used to be better than this. — Actually Three Guns (@NotThreeGuns) January 24, 2017

@rylandes @GolightlyGrl427 @joss And he supposedly supports women…I guess just the ones who wear fake vaginas on their faces — Ster (@Ster24080753) January 24, 2017

@joss wow calling his wife a dog? I guess it's OK to demean women as long as you don't like them or their husbands, eh? — Dick Gazinya (@JaDingo) January 24, 2017

@joss Maybe next time just come out and say "bitch". You ain't fooling anyone with "Pekingese". Is this how you fight for women's rights? — Priest Of Gamers 🕹 (@AndyFrogman) January 24, 2017

Whedon is no stranger to controversial comments. He once called for House Speaker Paul Ryan (R., Wis.) to be brutally murdered.

"Violence solves nothing. I want a rhino to fuck @SpeakerRyan to death with its horn because it's FUNNY, not because he's a #GOPmurderbro," Whedon wrote on Twitter.
