Rhys Ifans has been cast in the recurring role of Sherlock Holmes' older brother, Mycroft Holmes, in the Season 2 Premiere of Elementary, Thursday, Sept. 26 (10:00-11:00 PM, ET/PT) on CBS Television Network. For the first time, the premiere will be shot on location in London.

In the episode, Sherlock (Jonny Lee Miller) is called to London to revisit an old case, where he is forced to face his older brother, Mycroft. Although the siblings suffered a drastic falling-out a few years earlier, Mycroft allows Sherlock and Joan (Lucy Liu) to stay in his new home, 221B Baker Street. With Joan in the middle, the brothers are forced to confront their very complicated history.

Here's what series creator and executive producer Robert Doherty had to say about Rhys Ifans joining the cast.

"I could not be more excited to have Rhys coming aboard. 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' credits include the feature films The Amazing Spider-Man, Notting Hill, Anonymous, and the upcoming Serena.

Elementary is a modern-day drama about Sherlock Holmes and Dr. Joan Watson, a crime solving duo that cracks the NYPD's most impossible cases. Following his fall from grace in London and a stint in rehab, eccentric Sherlock escapes to Manhattan where his wealthy father forces him to live with his worst nightmare - a sober companion, Dr. Watson.

Elementary is executive produced by Robert Doherty, Carl Beverly, Sarah Timberman and Craig Sweeny, and is produced by CBS Television Studios. It is distributed internationally by CBS Studios International.
