Identify this 70 / 80s horror film for me please

[alfa pint]

I'm trying to track down a film from my childhood, which I think I saw as an 11/12 year old lad back in the very early 80s.

The plot, as much as I remember of it, involved humans being grafted onto animals and vice versa. There was definitely some bit with a human with a dog's head. The lead actor spent the film on the run away from the mad scientists who did it.

Nasty twist (probably really obvious to an adult) at the end when the protagonist wakes up and realises that he's been operated on and is now half animal.

Sorry I can't be more specific, but it was 30 years ago! Any help gratefully received.

O Lucky Man?

Scenes of animal experimenting like that going on there.

Edited for the picture.

The Island of Dr Moreau?

A bit of intense searching suggests it might be the Twilight People from 1973, but there's only the trailer on you tube. Very island based, similar to dr moreau, yet the memory I have of the film was more urban, including the lead character hiding in cellars.

Definitely not o lucky man, although I nearly shat myself when I saw the pic as it's exactly the sort of thing I had in my head. Looks like a cracking film to watch when a little inebriated!
