The Producers star is playing the lead in The Starry Messenger but theatre-goers attending the play's first showing on Monday (26Oct09) were shocked by the actor's poor performance.
Broderick, who has tackled numerous Broadway plays including The Foreigner and The Philanthropist, reportedly forgot his lines throughout the production, leaving the audience fuming.
A source tells the New York Daily News, "It was an overall mess. He kept apologising under his breath after he forgot a line and everyone in the audience began to feel awkward."
The Starry Messenger will now open a week behind schedule on 23 November (09).
