Joker actor Joaquin Phoenix dropped by a screening of his new film at the Alamo Drafthouse in Los Angeles. He took time to meet with fans, answer questions and snap selfies.

Joker opened in movie theatres worldwide this week after winning the top prize at the Venice film festival last month.

With an estimated $93.5m (£75.8m) in tickets sales it has delivered the "largest October domestic opening ever" in the USA.
