Anna Gunn's off-Broadway show Sex With Strangers was cut short on Tuesday (15Jul14) after castmember Billy Magnussen was reportedly struck down with food poisoning.

The show was delayed after the interval and eventually called off due to the Boardwalk Empire star's illness, according to New York Post gossip column Page Six.

Attendees who missed out on half the show have been urged to contact the box office for tickets to another performance.
