President Obama and actor Leonardo DiCaprio will meet at the White House on October 3 to discuss ways to end climate change, the White House announced Sunday.

The meeting will be part of the White House’s new art and film festival South by South Lawn (SXSL).

Obama and DiCaprio will be joined by climate scientist Dr. Katharine Hayhoe for a conversation about “the importance of protecting the one planet we’ve got for future generations.” The conversation will be followed by a screening of the actor’s climate change documentary Before the Flood for guests on the South Lawn.

This won’t be DiCaprio’s first time meeting Obama; he reportedly visited the White House along with Martin Scorsese while the pair were filming The Wolf of Wall Street in 2013.

DiCaprio’s climate documentary premiered at the Toronto International Film Festival earlier this month.

The actor’s meeting with Obama in October comes as has has faced increased pressure to return donations made to his environmental-focused Leonardo DiCaprio Foundation. Some of the contributions to the Revenant star’s charitable organization have been linked in news reports to a $3 billion Malaysian embezzlement scheme.
