Benedict Cumberbatch sat down with ​Uproxx and dished on his role as Doctor Strange in the last Avengers movie. After talking about how he'll be playing The Grinch in the upcoming Dr. Seuss animated feature, Cumberbatch revealed that he does have one big regret about Infinity War.

"My biggest regret of that whole time is that I didn’t sneak in to see people’s reaction," Cumberbatch said. "And I wish I had. I really do. I really wish I’d done that."

He shared that "Mark Ruffalo took his children, because he then FaceTimed us from the cinema ... His teenage children’s friends are running in the aisles going, 'No, what’s happening!?' The universe had crashed around him, which is really cruel, but kind of really enjoyable."

The press tour was a long experience for Cumberbatch and he was just happy to finally spend time with his family. But he said that when his wife finally saw the film, even she was shocked. "​Baby, he’s gone," he told her. "There’s no more Doctor Strange. He’s gone. That’s it."

Cumberbatch was impressed by the effect the film had on audiences. "It’s amazing," he said. "People were really sucked in, but that’s great. Isn’t it amazing that stories can still do that?"

Avengers 4 will be in theaters May 3, 2019—and ​hopefully Doctor Strange will return.
