Actor Dan Bucatinsky has joined the NOH8 Campaign, which raises awareness and funds for gay rights causes, including ending California's 2008 voter-approved gay marriage ban, Proposition 8.

The campaign's Adam Bouska and his partner Jeff Parshley photograph celebrities, politicians, professional athletes and everyday folks with their mouths duct taped and the campaign's familiar “NOH8” slogan often written on one cheek.

In his photograph, Bucatinsky is wearing a white t-shirt and signaling to stop with his left hand.

The 47-year-old Bucatinsky is best known for starring in the 2011 romantic comedy All Over The Guy. In 2008, Bucatinsky, his husband, Don Roos, and Lisa Kudrow (Friends) co-produced the web series Web Therapy. Now in its 5th season, Web Therapy can be seen on Showtime.

Celebrities who have recently joined the NOH8 Campaign include actress Lana Parrilla, actor LeVar Burton, Minnesota Vikings punter Chris Kluwe, singer LeAnn Rimes, actor Taye Diggs, actor James Van Der Beek, actress Aisha Tyler, Glee's Nene Leakes, singer Miley Cyrus, Hot in Cleveland's Valerie Bertinelli, Wendie Malick and Jane Leeves, singer Courtney Love and Meghan and Cindy McCain.
