Amal Clooney did not attend George Clooney's opening night on Broadway so she could look after their children

According to People, George told reporters: "She's with the kids."

The 'Ticket to Paradise' actor previously noted that the schedule of a play meant that he still got to see his children for part of the day.

Speaking on 'The Late Show with Stephen Colbert', he explained: "Actually, a play is kind of a good schedule because you're working at night.

"You get to see the kids during the day, so it's okay."

The former 'ER' star previously explained that he was "honoured" to be taking on the role at the Shubert Theater as he tried something new in his career.

He said in a statement: "I am honoured, after all these years, to be coming back to the stage and especially, to Broadway, the art form and the venue that every actor aspires to."

He plays journalist Edward R. Murrow, who was originally played by David Strathairn in the 2005 film, while Clooney actually played his collaborator Fred W. Friendly.

He penned the journalism drama with Grans Heslov, and the pair will once again collaborate on the Broadway adaptation, although David Cromer is stepping into direct instead of the Hollywood star.

Cromer added: "Edward R. Murrow operated from a kind of moral clarity that feels vanishingly rare in today's media landscape.

"There was an immediacy in those early live television broadcasts that today can only be effectively captured on stage, in front of a live audience."

The historical drama focuses on 1950s television news in the United States, and the conflict between broadcaster Murrow, and Senator Joseph McCarthy.

Clooney is following in the footsteps of Steve Carell and Rachel McAdams, who made their own Broadway debuts last year following decades of Hollywood success.
