Hugh Grant Sent Jerry Seinfeld The Most Unexpected Text After Making Movie Together

Jerry Seinfeld clearly got a kick out of working with Hugh Grant on the upcoming movie Unfrosted: The Pop-Tart Story.

Hes so funny. And we had lots of fights, Seinfeld said during a Thursday appearance on The Tonight Show Starring Jimmy Fallon. 

Hes a pain in the ass to work with. Hes horrible, the comedian joked. He tells you before you work with him, Youre gonna hate this. And hes so right. 

In Unfrosted a comedy about the invention and introduction of the Pop-Tart in the 1960s, directed by Seinfeld himself Grant plays Thurl Ravenscroft, the actor who for decades supplied the voice of Tony the Tiger.

On The Tonight Show, Seinfeld recalled having dinner one evening with Grant, which he called the best night.

We shot for 10 weeks, and that night that he and I had dinner. And we got drunk, having dinner that was the greatest night, Seinfeld told Fallon. Cause hes so cool and hes that English thing, you know, that witty he looks good in a jacket.

Seinfeld explained that on Thursday, Grant even sent him a surprising (and dare we say sweet) text after viewing Unfrosted for the very first time.

Just watched the film. To my great surprise I liked it. Laughed out loud, the text from Grant said. All actors were good. Even you. Love, Hugh. 

Grant is known for his notoriously grumpy behavior, as attested by various co-stars over the years.

Drew Barrymore, who starred in Music and Lyrics alongside the British actor in 2007, described what its like to work with Grant.

You think youre getting this charming movie star, and what you really get is grumpy Hugh, Barrymore said on her show last year. And then you fall in love with grumpy Hugh.

Unfrosted is set for a May 3 release on Netflix .
