Wesley Snipes ordered to report to prison

The actor has until noon to surrender to the McKean Federal Correctional Institution in Lewis Run, Pa., officials told CNN.

Snipes, who was convicted for willful failure to file federal income tax returns, was denied a motion last week to remain free while appealing to the U.S. Supreme Court. He said Tuesday on Larry King Live that he was nervous about going to prison, but remains hopeful.

"We still have prayers out there. We still believe in miracles. So don't send me up the river yet," Snipes said. "I think any man would be nervous if his liberty is at stake. I'm disappointed that the system seems not to be working for me in this situation."

Snipes, 48, was convicted in April 2008 in Ocala, Fla., on three misdemeanor charges of failing to file his income tax returns from 1991 to 2001.

He said on Larry King Live that the failure to file was his advisers' fault and that he has always paid his taxes.

"The press hasn't reported that I was a client of people who I trusted [who] had knowledge and expertise in the areas of tax law that would protect my interests," Snipes said. "[The press] claimed that there was a certain number that was owed and that number has been all over that place. The press has escalated it and changed it a number of times. But we think we are fully compliant with what was owed. ... My position is that I always paid."
