The League star Katie Aselton has signed on to join Matthew McConaughey, Ken Watanabe and Naomi Watts in the upcoming drama Sea of Trees.

The story centers on Arthur (Matthew McConaughey), an American man, and a Japanese man named Takumi (Ken Watanabe) who meet in an area of Japan known as the "Suicide Forest," where many go to end their own lives. Instead of killing each other, the two men go on a journey of self-reflection through the forest together. Katie Aselton is playing a woman who had an affair with Arthur. Naomi Watts is playing Arthur's wife Joan.

Gus Van Sant is directing from a screenplay by Chris Sparling, with Gil Netter producing. It isn't known when production may begin.

Katie Aselton will return for The League Season 6 of The League, which debuts September 3 on FXX. On the big screen, she most recently starred in and directed the thriller Black Rock.
