The first season finale of CBS' modern Sherlock Holmes drama 'Elementary' threw a major wrench into Sir Arthur Conan Doyle's canon with the reveal of Moriarty's true identity, but it seems the acclaimed procedural will keep things a bit more traditional with the introduction of Sherlock (Jonny Lee Miller)'s older brother Mycroft. 'The Amazing Spider-Man' star Rhys Ifans will take the iconic role, but for how long?

According to The Hollywood Reporter, Ifans will first appear in character for the season 2 premiere, during which Sherlock and Joan return to London to investigate one of Sherlock's old cases. Despite a years-prior falling out, the two brothers will deal with their issues as Joan and Sherlock come to stay at Mycroft's iconic home of 221B Baker Street. It is believed Ifans will appear in a recurring role throughout the season.

"I could not be more excited to have Rhys coming aboard,” said executive producer/creator Robert Doherty. “I've always been a tremendous fan and feel very honored to have him in the fold. Equally excited are Jonny and Lucy, both of whom have worked with Rhys in feature films. I think this is going to be a lot of fun for all of us."

Ifans becomes the latest high-profile UK star to take the role of Sherlock's older brother, most recently portrayed by Stephen Fry in the Robert Downey Jr. film series and Mark Gatiss in the BBC's 'Sherlock.'

Well, what say you? Are you excited to meet more Sherlock Holmes favorites in 'Elementary' season 2? What do you think Rhys Ifans will bring to the role?
