John Lithgow has described his new film Love is Strange as a powerful love story that everyone can relate to.

The film, which opened Friday in New York City and Los Angeles, pairs Lithgow with Alfred Molina.

After 39 years together, Ben (played by Lithgow) and George (Molina) decide to exchange vows. Their marriage, however, causes Ben to lose his job as a longtime choir director for a co-ed Catholic school.

Speaking to gay male entertainment blog, Lithgow said the film's centerpiece was its romance between his character and Molina's.

“The most vivid thing about the film is this love relationship. I always say, it's a movie with one starring role that's played by two actors. The starring role in this film is a marriage,” Lithgow said.

“It's about that particular kind of intimacy. Love that has lasted for 40 years.”

“It's cranky and uncomfortable sometimes, but these two people are completely essential to each other. And the fact that they're two old gay men just makes it extraordinarily unusual. You just don't see that relationship portrayed in movies.”

Marisa Tomei, Cheyenne Jackson, Darren Burrows and Charlie Tahan also appear in the film.
