Uma Thurman: Robert Pattinson is a really good actor
Speaking to MTV News, Thurman said she believes he will be a "really serious actor".
In Bel Ami, which also stars Christina Ricci, Pattinson plays a young man, who rises to power in Paris by manipulating some of the city's influential and wealthy ladies.
The Oscar-nominated actress said: "I think he's incredibly concrete in his presence on the set and obviously is very handsome.
"[He] is a very nice person and he's sensitive. He's present ... He's a really good actor."
Thurman, who received a best supporting actress Academy Award nomination for Pulp Fiction back in 1994, added that Pattinson has a great deal of "weight to him".
Pattinson will also appear in this year's The Twilight Saga: Breaking Dawn – Part 1, where he stars alongside Kristen Stewart and Taylor Lautner.
