Focus Features has released the first trailer for the mature coming out gay film Beginners starring Christopher Plummer and Ewan McGregor.

Writer-Director Mike Mills' Beginners features 80-year-old Plummer in his first gay role.

Oliver (played by Ewan McGregor) tells the story of his father, Hal, trying to catch up on lost time after coming out gay at the age of 75. Hal begins to openly embrace his sexuality by socializing with other gay men and dating a man about the same age as his son (Goran Visnjic).

Hal is also attempting to reconnect with his son after being told he's terminally ill. (The video is embedded in the right panel of this page.)

The film premiered last year at the Toronto International Film Festival and lit a bidding war for distribution rights. Focus Features, the company that brought us Milk and Oscar-nominated The Kids Are All Right, acquired worldwide rights, excluding Canada, France, Australia, Scandinavia and the Benelux nations.

Focus Features recently acquired worldwide rights to the lesbian teen drama Pariah, which premiered last week at the 2011 Sundance Film Festival.

Beginners is partially based on Mills' own true-life experience with his father. The film opens in June.
