It's got more gunplay than your local post office, enough close-ups of the female posterior to make Sir Mix-a-Lot blush, and so many dirty words it'll likely be banned before you finish reading this sentence. Quentin Tarantino and his motley crew call it "Hell Ride," and it sure is one helluva something.

What, exactly, depends on your own personal tolerance for murder, mayhem, mud-wrestling and Michael Madsen in a tree, doing an owl imitation.

The flick, which premiered this week at Sundance, follows two warring biker posses. Set in a surreal world where every woman wants a roll in the hay, and every man knows he can shoot another man in the crotch without any fear of interference from the police, it revolves around three keys labeled "666," the 1976 murder of a biker babe and a whole lot of vengeance.

Earlier this year, "Easy Rider" icon Peter Fonda paid tribute to his motorcycle movie lineage with an enjoyably evil role in "Ghost Rider." Now, his legendary partner-in-crime is eager to do the same...with some help from Quentin Tarantino. "I am doing a motorcycle movie this year that Quentin Tarantino is producing," Dennis Hopper told us this week, confirming rumors that he'd been cast in the currently-filming action film "Hell Ride," which co-stars the pic's writer and director, Larry Bishop.

The old-school flick, which tells the story of three tough guys (veteran "Kill Bill 2” actor Bishop, Michael Madsen and "24” heartthrob Eric Balfour) settling a score between them, is described as a modern day "The Good, The Bad and the Ugly," and is currently filming in the Los Angeles area. "I am playing Eddie 'Scratch' Zero," laughed Hopper, a "Blue Velvet"-like wickedness growing across his face. "And I couldn't possibly begin telling you who that is, but he is weird enough."

Adding that "I know Quentin and I love all of his work," the actor who so memorably delivered Tarantino's dialogue in "True Romance" added that when Tarantino and Bishop asked him to hop back on a hog one more time, he couldn't say no.

In other news, Hopper revealed to MTV that he hopes to step behind the camera again soon. "I am going to direct another movie this next year," said the tireless counter-culture icon, who recently turned 71. Hopper also will be seen in two more films coming out later this year. "I just did a thing with Charlize Theron, who produced her first movie," he said of the drama. "I play her father in it, and it's a terrific thing called 'Ferris Wheel.' [Another is] a wonderful thing with Penelope Cruz and Sir Ben Kingsley called 'Elegy,' based on the Philip Roth novel 'The Dying Animal,'" Hopper said of the impressively-cast sexual drama, which also includes Patricia Clarkson, Deborah Harry and Peter Sarsgaard. "I play Ben Kingsley's best friend. We are both womanizers and college professors, and I am giving him advice on how to have an affair with a younger woman."
