The butt-dial seen round the world. Mark Ruffalo accidentally left his phone streaming to Instagram Live for an audience of 2,500 Tuesday night.

Not a big issue normally, but he happened to be sitting in the audience of the L.A. premiere of Thor: RagnarokMarvel’s next big superhero movie.]

Before the film started, he joined his Thor costar Jeff Goldblum onstage to greet fans. He used Instagram Live to show viewers at home how many Marvel fans had shown up to see the film. Then he put his phone in his pocket forgetting to cut the stream.
