Richard Gadd is stepping out for the premiere of his new HBO series.

The 36-year-old Emmy-winning actor was joined by co-stars Stuart Campbell and Mitchell Robertson at the Half Man premiere on Thursday night (April 16) held at Regal Union Square in New York City.

Fellow cast members in attendance included Neve McIntosh and Julie Cullen.

Here’s the synopsis: “Niall (Jamie Bell) and Ruben (Gadd) are brothers. Not related in blood but the closest you can get. One, fierce and loyal. The other, meek and mild-mannered. Inseparable youth. Brought into each other’s lives through death and circumstance, all they have is each other… But when Ruben turns up at Niall’s wedding three decades later, everything seems different. He is on edge. Shifty. Not acting like himself. And soon, an explosion of violence takes place which catapults us back through their lives, from the eighties to the present day.”

Keep reading to find out more…“Capturing 30 years in the lives of these broken men, HALF MAN is a six-part limited series exploring brotherhood, violence, and the intense fragility of male relationships. After all, when things fall apart… it is sometimes the closest relationships which break the hardest.”

Along with starring in the new series, Richard also serves as creator, writer, and executive producer.

Half Man premieres Thursday, April 23 at 9pm ET on HBO and will be available to stream on HBO Max. New episodes will debut weekly through Thursday, May 28. Watch the trailer here!
