Dr. Phibes Rises Again (1972)

Dr. Phibes Rises Again (1972), directed by Robert Fuest.

You don't get rid of Phibes that easily. When the stars are right he rises again and assisted by the mysterious and mute Vulnavia -- what the heck is she anyway? -- strives to get his dead wife to Egypt where she can be revivified.

It's more or less the same as The Abominable Dr. Phibes (1971), with comically ghastly murders against an art deco fantasy background. Pretty mild fun these days.

The actress who played Vulnavia in the first film was pregnant and unavailable this time so they brought in Miss Australia.

The photo of Victoria Phibes in both films is the uncredited Caroline Munro:

The desert locations were filmed in Ibiza, Spain.

The wikipedia article has plot summaries of more Dr Phibes sequels which were never made.

Available on Blu-ray.
