Sherlock star Benedict Cumberbatch was back at work two days after announcing he had become a father.
The actor, who was named a CBE in the Queen's Birthday Honours list for services to the performing arts and charity, announced the arrival of a "beautiful son" with his wife Sophie Hunter on Saturday.
He started rehearsals for his performance in the title role of Hamlet today.
The performance in a new production at the Barbican in London, which will run from August to October, will be Cumberbatch's first stage role since 2011 when he played Frankenstein at the National Theatre.
That performance won him a best actor honour at the Olivier Awards which he shared with Jonny Lee Miller, with whom he alternated roles in the play.
The cast also includes Game of Thrones star Ciaran Hinds as his uncle Claudius and Anastasia Hille as his mother Gertrude.
Cumberbatch missed out on winning the best actor Oscar this year, his stock as an actor having risen considerably following stand-out roles in the sleuth detective series.
His early career was steadily successful with roles in weighty dramas such as To The Ends Of The Earth and Small Island, but his life changed forever when he picked up the deerstalker and signed on to play Sherlock Holmes in the BBC's updated take on the classic crime stories.
The show made him a star around the world with fans from China - where he was dubbed Curly Fu - to the studios of Hollywood who marked him out as one to watch.
They soon signed him up to star in Star Trek: Into Darkness and 12 Years A Slave, with both films benefiting from the attentions of his global army of fans who jokingly refer to themselves as ''Cumberbitches''.
They also flocked to cinemas to see him as tortured code-breaking genius Alan Turing in The Imitation Game - the role which saw him nominated for the leading actor Oscar.
Cumberbatch and Hunter announced their engagement in a notice in The Times newspaper in November last year and they tied the knot in a private ceremony three months later.
The couple met when they appeared together in the 2009 film Burlesque Fairytales.
