You probably remember Michael Welch from the Twilight saga, about a girl torn between vampire and werewolf boyfriends (Robert Pattinson, Taylor Lautner). He plays a human who has an unrequited crush on her.
Michael had sharp features and striking eyes that make him look angelic, demonic, or alien, so he was often cast as a gay-vague outsider, even if his characters sometimes experienced unrequited heterosexual passions.
He began his acting career at the age of 10 in Star Trek: Insurrection (1998) as Artim, a guy from a non-technological planet who bonds with the android Data. performance won him a Young Artist Award.
Next came a series of paranormal and science fiction roles, including a clone of Colonel Jack O'Neill (Richard Dean Anderson) who just wants to be a normal teenager, on Stargate SG-1.
He guest-starred in a number of sitcoms and dramatic series, including a memorable role as a new neighbor who falls for the brainy Malcolm in Malcolm in the Middle.
On Joan of Arcadia (2003-2005), Michael plays Luke Girardi, genius brother of the girl who talks to God, He has a homoromantic buddy-bond with his best friend Friedman (Aaron Himmelstein), although he's also girl-crazy.
In The United States of Leland (2003), his mentally-challenged Ryan is murdered by classmate Leland, Ryan Gosling, who is dating his sister.
The Grind (2009) is about a grifter, Luke (C. Thomas Howell), who depends on his friends Josh and Courtney (Michael, Tanya Allen) to get him out of a jam. They start a sleazy website, but things go sour, and Luke has to rescue them from the Mexican mafia.
In Lost Dream (2009), college student Perry (Michael) falls for nihilistic free-spirit Giovanni (Shaun Sipos), who is involved in risky sex, drugs, and games of Russian roulette. He must save Gio before it's too late.
As we often find, teenage gay-subtext roles give way to a thoroughly heteronormative adulthood. Hansel and Gretel Get Baked, 2013, about a witch who lures teenagers into her house and drugs them with marijuana before literally baking them for dinner.
