On Tuesday night, Mark Ruffalo accidentally streamed a portion of Thor: Ragnarok (audio only) from the LA world premiere. Apparently, he forgot to turn off his Instagram live when it happened.
The actor received a huge applause as he was introduced at the premiere screening at the El Capitan Theatre. He briefly recorded the audience to capture the moment, but then forgot to turn it off before putting it back in his pocket.
Around 2,500 people saw the live stream and commented over how long it would take before Ruffalo ended the broadcast. The whole time, the audio recording was crystal clear. He stopped it at around 8:15 p.m.
