Darren Criss, who plays Blaine Anderson on "Glee," made his debut on Tuesday night in the Broadway musical "How to Succeed in Business Without Really Trying."
Criss took over "Harry Potter" star Daniel Radcliffe's role of J. Pierrepont Finch, a window washer who aims to climb the ranks at the World Wide Wickets Company in New York City. Criss will appear in the show, which marks his Broadway debut, until January 22, when Nick Jonas will take over.
Criss made his "How To Succeed" debut to a sold-out crowd and was joined on-stage by Beau Bridges, who also made his debut in the musical.
The 24-year-old "Glee" actor greeted a mob of fans after the show and told them, "Anybody that can hear the sound of my voice. Thank you from the bottom of my heart. This is a very special night for me, so thank you," reports OK magazine.
The New York Daily News said of his performance, "Darren - unlike the guy he plays - doesn't need to consult a book for pointers on how to succeed. He could write it."
Criss rehearsed during a break from filming "Glee" and told fans on Twitter, "So I've been gone from the Internet for the past two weeks- been busy getting ready and excited for my opening of 'How To Succeed' on B-Way!"
The musical is based on a satirical self-help book and stars Beau Bridges as J.B. Biggley, the president of the firm. Radcliffe, 22, has played Finch since the musical, a revival of a 1960s show, opened in previews in February. He departed the show on January 1, when his contract was set to end.
On "Glee," one of the FOX network's most successful shows, Criss' character was a leading singer of a rival club who got involved in a relationship with a male member of the main glee club and transferred schools. The San Francisco native has said that as a child, he listened to cast record recordings of musicals such as "Les Miserables" as well as pop songs. When he was older, he began writing and performing music and was discovered from his YouTube videos, which ironically included one called "A Very Potter Musical," based off of Radcliffe's "Harry Potter."
