Not one of my fellow horror loving friends have seen or even know of this movie. I saw it on TV in the 80's or 90's, got a copy on VHS,later sold it but then find myself buying another one as it doesn't appear to be easily available on disc (it really does deserve a release).
The late, great Donald Pleasence is a brilliant but crazed scientist working on mutating humans with plants (in his lab he has a laughably bad rabbit eating plant!). He is aided by the hideously disfigured Tom Baker (of Dr Who fame), who runs a circus freak show.
Many real freaks (probably an incorrect word these days) were employed, in addition to obviously fake ones. No attempt is made to hide the fact that this was in part inspired by the original 1932 classic "Freaks", to the point where the "one of us" line is used.
Add to the mix nudity, 1970's London locations, LSD references, time lapse photography sequences, a few amusing gaffs and a pretty haunting musical score, this is an enjoyable slice of British exploitation. Not to everybody's taste, for sure, but this film deserves to be better known.
