Jude Law is My Dear Watson

Jude Law leaves his home in London on Wednesday, sporting a mustache that he is growing for his new role in Sherlock Holmes.

The 35-year-old British actor was then spotted using his cell phone while driving his Mercedes.

Jude is currently filming for Sherlock Holmes, where he plays Dr. Watson. Robert Downey Jr. was cast as Sherlock Holmes, and Rachel McAdams as Irene Alder, a femme fatale.

Set in 1891, the film revolves around Holmes and Watson stopping a conspiracy to destroy Britain.
