Sylvester Stallone an encyclopedia of literature: co-star

'Selma' star Tessa Thompson, who is currently making a new 'Rocky' sequel, 'Creed', with Sylvester Stallone called the actor an encyclopedia of literature.

Thompson, 31, was attending a Fashion Week here when she made this revelations, reported New York Post.

"He is kind of an encyclopedia of literature and film knowledge. He'll, like, sit and quote Voltaire. He is constantly cracking jokes, he's really fond of riddles," Thompson said.

But despite the hidden depth, "he's always keeping the energy light and telling anecdotes about the other ('Rocky' movies) they've made", she added.

While on a break from shooting, Thompson attended a Jenny Packham fashion show at Industria Superstudio and saw Dave Chappelle perform at the Gramercy Theatre.
