most psychedelic mainstream movie?

A couple of months ago, after a rather grueling week, my girlfriend and i decided to zone out and watch an old Disney film. After some debate, we settled on Dumbo. When the “pink elephants on parade” scene came on, we both sat there in disbelief. “This is a kids movie!? From the 40s!? Whaaaa?” But then i realized that kids would probably enjoy it too, and probably wouldn’t need any special substances to do so.

I suspect there are numerous other Disney films that could contend, whether accidental or not.

Assuming films like The Wall and** Head** don’t count:

Willy Wonka and the Chocolate Factory, starring Gene Wilder. The scene with the pink boat in the tunnel, with Gene yelling, was pretty trippy.

For a hit of psychedelic fun, I recommend the 1970 kiddie film Pufnstuf and the TV series upon which it is based.

The OP may have nailed it. Pink Elephants remains a remarkable piece–inventive, funny, brilliant animation, clearly ahead of its time, and incredibly trippy. Not the first cartoon to employ surrealistic imagery, but the first to take full advantage of color and a no-holds-barred approach to what could’ve been a predictable “dream sequence”.

Things like Willie Wonka or the stargate sequence in 2001 are honorable mentions, but it’s one thing to be influenced by psychadelic culture and it’s another to anticipate it decades in advance.

heh heh

I think a lot of ‘kid orientated’ entertainment would count as kind of trippy.

Fantasia has some weird stuff. Really Beauty and the Beast is pretty funky. “Ok, you’re a clock and a candlestick and you both talk. Riiiiiight”

Or maybe The Wizard of Oz?
I’m not sure if you consider it mainstream but City of Lost Children is pretty surreal.

Holy crap. Jack Wild was 28 years old when he did that. How old was Jimmy supposed to be?

How “mainstream” was Zardoz?

Wow, it’s been at least 10 years since I saw that, and I’d forgotten how strange it really is. Somehow I don’t think it would make it into any of Disney’s modern day offerings.

200 Motels. The visuals trump everything else, and you have to be pretty stoned to figure out what’s going on.

“Red man-panties, gun-vomiting hot air balloon stone heads, flying books on fishing line, neat-o dance numbers (or at least ballroom catharsis), magic marker facial hair, elitist-hippie government, inexplicable backward-masking (check out Friend in the kitchen), the ugliest bride in the history of cinema, cool jewelry, the Internet before the Internet was the Internet (or even computerized), Big Brother, HAL, and David Niven merged into one, lots of flowy sheer curtains, EXCELLENT decorating ideas, nifty forms of mass transit, a profound sense of anatomy, and, perhaps most chillingly, an apocalyptic warning that, if we do not change our ways, we face a future COMPLETELY DEVOID OF UNDERGARMENTS.”
Woah. I don’t think I’m old enough to see that.

Not exactly mainstream, but “Forbidden Zone” is pretty damn weird. “Mondo Cane” is a classic movie to freak out to.

As psychedelic as “200 Motels” is, Zappa was distictly anti-drug. Well, except for caffeine and nicotine. It makes a good double feature with “Head.”

My vote would be for Disney’s Alice In Wonderland. I mean, what the hell?

Fear and Loathing in Las Vegas

Eraserhead. After numerous viewings, I’m still not sure what the deal is.

Of course the first movie I thought of when I saw the thread title was Dumbo. The second was Greaser’s Palace.

–although now that I think on it a little more,* Altered States *is probably closer to the letter of the OP.

Natural Born Killers has some very surreal moments.

The last 20 minutes of 2001: A Space Odyssey.

Not just psychedelic, but many other kinds of substances too!

  1. (born 1952, movie in 1970.)

How about the Flash Gordonmovie from the 1980? Barbarella? Oh, and according to imdb, a remake of Barbarella is in development.
