Marcia Cross joins cancer telethon
Marcia Cross is set to join more than 100 celebrities for the Stand Up To Cancer telethon in the US.
The Desperate Housewives actress, Diane Lane, Mark Harmon, Kyra Sedgwick, Jay Leno and Ryan Seacrest have also been added to the list for the hour-long fundraiser.
Other previously announced stars include Sally Field, Kareem Abdul-Jabbar and George Clooney.
Stand Up To Cancer will be hosted by news anchors Katie Couric, Diane Sawyer and Brian Williams and will be simulcast commercial-free by ABC, CBS, Fox, NBC and a number of cable channels.
Donations to the telecast are intended to fund innovative cancer research. The first telethon, in 2008, helped raise more than 100 million dollars.
