Spartacus star Andy Whitfield dies. Andy Whitfield, the Welsh-born actor who played the lead role in the TV series Spartacus: Blood and Sand, has died at age 39. Whitfield died on Sunday in Sydney, Australia, 18 months after he was diagnosed with non-Hodgkin lymphoma, manager Sam Maydew told the Associated Press.
Spartacus was a Thracian gladiator who led a slave revolt with an army numbering in the tens of thousands. He defeated Roman forces over half a dozen times, marching his people up and down the Italian peninsula until he was killed in battle in April 71 B.C.
