There were rumours that Darren Criss would replace Daniel Radcliffe in How to Succeed in Business without really trying but not it has been confirmed! Daniel Radcliffe's last performance will be January 1, 2012, after which time, Darren Criss will take over for at least 3 weeks.
LA Times writes:
Darren Criss, who plays the character Blaine Anderson on Fox's "Glee," will make his Broadway debut in January after Daniel Radcliffe leaves the Broadway revival of "How to Succeed in Business Without Really Trying."
Organizers confirmed Monday the rumors that Criss will take the lead role of J. Pierrepont Finch in the musical, playing at the Al Hirschfeld Theatre. Radcliffe is scheduled to leave the show Jan. 1, and Criss will step in for three weeks from Jan. 3 to 22. It's unclear if the musical will continue beyond that date, though at least one report indicates that the producers want it to.
It's so ironic, since Darren Criss first made himself known from doing the Harry POtter Musical on youtube, and now he is taking over for "Harry Potter" on broadway!
