OKLAHOMA CITY - A Hollywood actress is voicing her support for an Oklahoma death row prisoner who she claims is "clearly innocent."

Richard Glossip is scheduled to be executed next month for hiring the hit man who killed Barry Van Treese in 1997.

Glossip always has said he was innocent, and now, Oscar-winning actress Susan Sarandon is trying to get his execution stayed.

In an interview with "Sky News," Sarandon said there's no physical evidence tying Glossip to the murder.

She says the actual murderer pointed the finger at Glossip to get a lighter sentence.

Sarandon says Oklahoma Gov. Mary Fallin is a "horrible person," and she wants people to write Fallin letters asking her to intervene.

The Governor's office told us today she does not have the authority to grant Glossip clemency and the most she can do is grant a 60-day stay of execution.

As for the "horrible person" comment, they say they will not respond to name calling.

Glossip's attorney filed an appeal with the U.S. Supreme Court.
