Ben Affleck and his 10-year-old daughter Violet pose for a photo backstage with the cast of the play Harry Potter and the Cursed Child over the weekend in London, England.

The 44-year-old actor wasn’t the only star in the audience at that performance. He was joined by his Suicide Squad co-star Margot Robbie, as well as Darren Criss.

The play has been a sold out smash hit and tickets are nearly impossible to come by. Seats are going for thousands of dollars on the secondary market and according to reports, the theater is denying admission to people who they know bought the tickets through a scalper.
