Fun at times but it is more cheesy than anything.
Ursula Andress is effulgent in the title role and much more attractive than the modern day "She Who Must Be Obeyed", M Thatch.
Ursula's perfectly adequate in the title role (although I'm more of a Raquel Welch man, myself); Andre Morell has a small-but-effective supporting role. Cushing & Lee both have EXCELLENT beards in this! (Although, of the two, Cushing wins hands down.) Cushing and Cribbins would again team up, of course, in the following year's Daleks: Invasion Earth 2150AD.
The name of Chris Lee's character won't fail to raise a chuckle amongst those who know their rock'n'roll history.
And was the cage-lowering-into-lava-pit an inspiration for Temple Of Doom? Wouldn't surprise this viewer.
