Sandra Bullock has been proudly showing off video of her son Louis during preparation for her new movie.
The actress' Extremely Loud And Incredibly Close co-star Viola Davis revealed how the Oscar-winning actress is clearly "a great mother".
"He's always with her, she is so happy to be a mum," Viola revealed at the Hollywood premiere of her new film Trust.
"I've only just started with the make-up test, but we're already bonding," she explained.
"She is such a beautiful person and she's so proud to be a mum. She's showing video of him laughing, it's a beautiful, happy baby."
Sandra isn't the only big name in Extremely Loud And Incredibly Close, which tells the story of a nine-year-old who is searching New York for the lock that matches a mysterious key left by his father, who was killed in the September 11 attacks.
"I'm also working with Tom Hanks," Viola said.
"Whatever you think about Tom Hanks when you watch his movies - that he's kind of this great everyman, kind and humble - that's who he is.
"He's pretty much perfect!"
