The “War Horse” actor admitted that the only trouble he had while on set was keeping a straight face when he saw his friend and “Sherlock” co-star Martin Freeman in costume as lovable Hobbit Bilbo Baggins.

‘It was great. I got to hang out with him, and I kept a straight face for a bit and then I started giggling because I know Martin, I don’t know Bilbo,’ Cumberbatch said with a grin. ‘For Martin to be sitting there playing Bilbo is amazing. He’s going to be amazing, he’s going to be fantastic in this film.’
