Leonardo DiCaprio took an evening off from his Instagram boyfriend-ing on Wednesday to celebrate the premiere of his new climate change documentary Ice on Fire.

The HBO doc, which premieres on June 11, features the environmentalist actor as narrator and producer, while his father, George DiCaprio, served as executive producer.
