Contemplate This On the Tree of Woe!
Conan was crucified in "A Witch Shall Be Born" when he opposed the reign of Salome as "Taramis". Constantius had Conan crucified in the wilderness on an actual cross. He hanged there a few days but he's badass. He doesn't easily die. He even kills a vulture with his teeth! He survives for days without water. Seven months later, he crucified Constantius on the same spot... an epic revenge!
In the movie, the movie version of Thulsa Doom has Conan crucified on the Tree of Woe and nearly dies. To save his life, an heavy toll was exacted. To save Conan from near death, Valeria really dies. I found the movie crucifixion more realistic than that of the comics.
On the other hand, if the movie Thulsa Doom wanted to increase Conan's agony, he should have crucified Conan near Eric Idle. I think it could have been worse if Conan had to deal with his ordeal right next near to Eric Idle!
