Glee alum Kevin McHale and Dylan Walsh (Unforgettable) have booked recurring roles in When We Rise, ABC’s seven-episode event limited series about the gay rights movement, written and executive produced by Dustin Lance Black.

When We Rise chronicles the personal and political struggles, setbacks and triumphs of a diverse family of men and women who helped pioneer a chapter of the U.S. civil rights struggle.

McHale will play AIDS activist Bobbi Campbell. Walsh is Dr. Marcus Conant, a role based on leading American dermatologist Conant, a pioneer in the diagnosis and treatment of AIDS.

McHale starred as Artie Abrams on all six seasons of Fox’s Glee. He also stars in Hallmark Hall of Fame movie Hear My Song opposite Dustin Hoffman, set to premiere April 16 on CBS. He’s repped by Greene & Associates Talent Agency and M/C Talent Management. Walsh will next be seen in indie feature C Street and recently wrapped his role as Al Burns on crime drama series Unforgettable. He’s repped by Gersh and manager Bob McGowan.
