MANILA, The Philippines — An indie drama that explores the loneliness and missed opportunities of an ailing, 70-year-old gay man is testing Philippine sensibilities about sexuality and, if it passes the Academy Awards’ nomination process, may get a shot as the country’s entry in the best foreign-language film competition next year.

Bwakaw, or Voracious, has received positive reviews and local awards, and is doing the rounds of international film festivals in Toronto, New York, Hawaii, and Tokyo.

Writer and director Jun Robles Lana says the movie is named after a stray dog with a voracious appetite for life that Rene, the main character, strikes a friendship with. Bwakaw’s zest for life contrasts with Rene’s grumpy disposition.

Rene, who came out of the closet in his twilight years, thinks it is too late for love and only awaits his own death. He has made a will and labelled his few possessions to be given away to his few friends. He even bought a coffin at a funeral home’s closing-out sale.

But when Bwakaw dies after an illness, Rene, played by veteran actor Eddie Garcia, finds new appreciation for life. "It’s the dog that basically teaches him to live life to the fullest," Lana said in an interview.

"It’s really more about loneliness, although you can’t help that some people or critics are branding it a gay film simply because the character is gay, but that’s really beside the point," he said.

Lana admits that while Filipinos are generally gay-friendly — the most popular movie star is Vice Ganda, an out-and-out gay comedian — local mainstream audiences might not be too receptive to a serious take on homosexuality in the conservative and predominantly Roman Catholic society.

"We tend to look at gay characters as iconic, funny characters," he said. "So when you make a movie like this, you really have to market it in such a way that it would be more appealing to them."

He said that the movie focuses on the comedy aspect in order to appeal to a wider audience.

But the filmmaker hopes that between the laughs, moviegoers will find that it is more than a comedy.

He said he made the film with the intention to honor his mentor, writer Rene Villanueva, who died in 2007. He described Villanueva, who came out as gay later in his life, as generous and harsh at the same time, and an inspiration for the main character, Rene.

Lana said the drama "eventually became a story about growing old, missed opportunities, about how desire is inextricable from our lives."

For Lana, who started in art house films but has for the last few years been mainly involved in commercial movies,Bwakaw was also "a return to my roots."

"I did not expect this film, which I made for very personal reasons, would resonate with so many people and not just Filipinos," he said. "I’m really just thankful for all the wonderful things going our way."

The Philippines has submitted entries to the Academy Awards for many years but has never been nominated or even short-listed.

There are presently around 40 entries for the best foreign-language category. The list is to be pared down to 10 films late this year, and to five nominees by January.
