While doing promo for her movie 'Still Alice' Julianne Moore spoke to Inquirer Entertainment and had some very nice things to say about Rob and working with on Maps to The Stars with him.
"“Robert’s looks belie who he is inside. He has this formidable, very beautiful face. He’s such a gorgeous guy. He looks like he would be remote, but the minute I met him, he was very chatty. He’s very funny. He’s knowledgeable about film. He loves acting, actors and movies.Source
“Robert talked the entire time. I have to say I was shocked because I didn’t expect it. I mean, he’s so friendly, truly delightful, smart and talented. I loved him right away!”"
