Okay, I'm in a big minority, but in my view the cheap horror flick is very shrewdly done. Except for a hammy Albert Cole as Cass, the acting is pretty good, with Dern refusing temptation to go over the top. Also, the hulking John Bloom amounts to a casting inspiration. His massive frame dominates every frame he's in. Plus he manages the difficult role of the slow-witted in convincing fashion. Staging takes place in the boondocks where there's more bang for the buck, and while the massive monster may be too slow to be scary, the shrewd camera angles make the two-headed effect more credible than expected. Oh sure, the movie's title is a tip-off to the target audience. Still, I wouldn't put it in the same league as the rubber monsters of Roger Corman yore. Good to see an elderly Berry Kroeger picking up a payday. Was there ever a better shyster lawyer in a slew of 40's noirs than the moon-faced actor. And speaking of cast, blonde leading lady Pat Priest could double for Doris Day in her bouffant heyday. Anyway, I found the flick mildly entertaining and not as hokey as I expected. And before I forget—is there ever a menaced girl in these movies who isn't scantily clad and sexy. Certainly not here

Terrifically horrible exploitation movie that involves sewing the head of a fugitive/perv, onto a giant retarded farm boy. What could go wrong with that idea?The production values are more obtuse than anything you'll ever see. True to the exploitation genre, whenever an answer has been supplied for why people don't act more sensibly, the film-makers just move on; no matter how weak the answer was. i.e. After you've been kidnapped by a perv-escapee and seen him killed, what could be more natural than rushing off to take a nap? In the course of about five minutes, 4 characters fall down and are out cold, just as the plot requires them to be. I love that two characters (after witnessing a dual-strangulation by a two headed freak) have nothing to say to each other as they quietly watch the perpetrator walk away. I love that the movie imagines that horny sociopaths lick their lips, bulge their eyes and laugh every time a woman comes into view. There is no actual "night" in this movies goofy conception of 'day for night' shooting. The movie is so unashamed of its teeming awfulness that it becomes sort of endearing. And finally, inept weirdo Bruce Dern is in a production suited to his talent. 'Incredible Two-Headed Transplant' will have you asking important questions like "What would I do if someone sewed a second head onto my body?" and "What night should I do my laundry this week?"

I am not sure if this is the worst movie ever made but it could be the worst I'v ever seen. Its not that the acting is bad or the script in no good...its a combinationof everything. Why does the crazy doctor's wife tolerate being locked up in a cage and then worry about his memory being besmirched at the "tragic" end of the movie?

Call me demented but I loved this absolutely silly piece of 1970s Drive-In schlock! Director Anthony M. Lanza only made one other movie as far as I know, one I've been wanting to see for years, a 60s biker flick starring Dennis Hopper and Casey Kasem called 'The Glory Stompers'. Kasem returns in this one to play the concerned best friend of "mad" scientist Dr. Roger Girard played by cult favourite Bruce Dern (Kasem and Dern had previously played brothers in another 60s biker movie 'The Cycle Savages', a trash classic I highly recommend.) Dern, just like those scientists in 'Donovan's Brain', has his own lab in his home which he conducts his own private research, assisted by his crippled mentor Dr. Max ('Demon Seed'). Research, by the way, involving head transplants. So when a psychopath (Albert Cole) escapes on a rampage and kidnaps Dern's pretty blonde wife (Pat Priest of 'The Munsters'), it doesn't take long to figure out that the Doc is going to be operating on him soon. Especially when there is a handy mental defective (John Bloom, from 'The Hills Have Eyes 2') available (his caretaker's son). Now Bruce Dern is one of my favourite 1970s actors ('Bloody Mama', 'Silent Running', 'The King Of Marvin Gardens'), and I'd watch him in just about anything, but this must be the stupidest movie he has ever been involved in! Disinterested viewers who don't enjoy 60s and 70s exploitation and monster movies may find it just TOO stupid to get into, but I thought it was an absolute hoot, and loved every minute of it!
