Mark Ruffalo participated in a priest sexual abuse protest outside the Cathedral of Our Lady of the Angels with his "Spotlight" team, including director/co-writer Tom McCarthy and co-writer Josh Singer on Sunday hours before "Spotlight" won the Best Picture award at the 2016 Oscars, according to The Hollywood Reporter.

They stood in support with members of SNAP (Survivors Network of Those Abused by Priests) in downtown Los Angeles, calling for the names of the abusers to be released.

"I'm here to stand with the survivors and the victims and the people we've lost from Catholic priest childhood sex abuse," Ruffalo told protesters, according to the Los Angeles Times.

Ruffalo was nominated at the Oscars for Best Supporting Actor for his performance in "Spotlight," a film inspired by the true story of a team of Boston Globe journalists who uncover the Catholic church's child sexual abuse scandal involving priests and its cover-up.

"Standing with the survivors of Priest sexual abuse!" Ruffalo wrote on Twitter. "Just got back from a protest with SNAP Priest Sexual Abuse Survivors," the 48-year-old actor captioned an Instagram picture of a flier from the protest.

 The #oscars aren't all fun and games. @markruffalo is out this afternoon supporting SNAPnetwork.org which supports survivors of priest sexual abuse. Mark stars in Spotlight, which chronicles the uncovering of the abuse. Lest you be cynical that this is a PR stunt, the academy votes are already in. This won't affect the outcome for the oscars, but it could for the survivors.
