This is what Martin Freeman (The Hitchiker's Guide to the Galaxy), who plays John Watson on Steven Moffat's new hit show Sherlock, thinks.
The British actor told What's on TV:
"I don't feel as passionate about Doctor Who as Stephen does, but I've enjoyed watching it more since being a father.Sherlock's first episode, A Study in Pink, garnered an impressive audience of 7.5 million viewers.
"We met Matt Smith while filming Sherlock in Cardiff because the Baker Street set is next to the [Who] set. It was strange seeing Sherlock Holmes and The Doctor together. They are the perfect fictional team."
The next episode, The Blind Banker, airs this Sunday on BBC One at 8h30pm.
