Dr. Michael McBain is a fictional character on the ABC soap opera One Life to Live currently being played by Chris Stack.
The role of Michael McBain was originated by R. Brandon Johnson in November 2003, with Nathaniel Marston assuming the role on February 16 2004 and ultimately leaving on November 29 2007. On January 9 and January 10 2007, Robert Harte temporarily filled in for Marston as Michael. Chris Stack took over the role of Michael starting December 3 2007.
Marston originally played the role of Al Holden from 2001 to 2004. Al is romantically involved with Marcie Walsh; when Al is killed off, fans of the couple organized a write-in campaign calling for Marston's return. Marston later returned to the series in a storyline in which Al's "spirit" helps Michael change his selfish ways and win Marcie's heart. Johnson and Marston alternated in the role of Michael as Al's spirit sometimes "takes control" of Michael. At the conclusion of the story on February 16 2004, Al's spirit takes over Michael's body permanently and loses all memory of Al's life; Marston assumed the role full-time.
