Barbarella is the 1968 Sci-Fi cult-classic starring Jane Fonda, John Phillip Law, Milo O'Shea, Anita Pallenberg, Ugo Tognazzi, David Hemmings, Marcel Marceau, and Claude Dauphin. It was directed by Fonda's husband at the time, Roger Vadim, and produced by the famous Italian producer, Dino De Laurentiis. It was based on and adapted from a French comic book. The movie itself is bad. The writing and acting are god-awful, and the plot is silly. It was mostly a comedy (or what passed for comedy in the late 1960s) and was very tongue-in-cheek and campy (similar to the 1960s Batman TV series). It did have some (very bad) action, a slight political message, and a heavy anti-war message (based on the free-love hippie culture of the time). Of course, Fonda would become a highly controversial figure in the 1970s due to her protests against the Vietnam War, including visiting Hanoi, the capital of North Vietnam.
Despite having a very high budget (for the time), everything about the movie looks cheap and fake. Obviously, special effects in the late 1960s were nothing like what they are today; however, if you compare this film to the other major Sci-Fi classic that came out the same year, 2001, the difference is night and day. However, the movie does feature Fonda (who was an absolute smoke-show back then) in skimpy revealing outfits, and nude during the opening credits. Sadly, Fonda actually had an eating disorder at the time the movie was being made, so the outfits they put her in probably did not help that. The plot involves Barbarella (played by Fonda), who is a space traveler and representative of Earth (which, at some time in the future around the year 40,000, has become a peaceful utopia), being sent to the Tau Ceti planetary system to track down a rogue scientist named Durand Durand (played by O'Shea), who has created a weapon with the power to destroy humanity. There, she has sex with pretty much everyone she meets in exchange for help tracking Durand down.
The 4K set is a two-disc set, containing a UHD disc and a standard Blu-ray disc. The A/V quality is very good, but it definitely exposes the limitations of the late 1960s special and practical effects. The UHD disc contains the movie and a handful of extras (alternate opening and closing credit sequences). The movie can be played with an audio commentary track by film critic Tim Lucas. The standard Blu-Ray contains hours of bonus content, most of which was produced in 2003 specifically for the 4K release by Arrow Films. The longest feature is a zoom discussion between Tim Lucas and comic book artist Steve Bissette, in which they discuss the movie, the comic it was adapted from, and the influence it had on similar films and comics, and pop culture in general (such as inspiring the name of the 1980s British pop group, Duran Duran, which was probably the best thing that resulted from the film's popularity). Additionally, the release includes behind-the-scenes footage, photo stills (which feature both promotional and behind-the-scenes images), interviews with some of the surviving cast and crew members, the theatrical trailer, and radio spots. Notably, Fonda does not appear in any of the updated bonus features.
Ultimately, the movie is a product of the late 1960s that does not hold up particularly well, aside from being a cult classic. It is not necessarily a movie that you will watch because you want to see award-winning entertainment (unless you count the Razzies), but it is entertaining in its own way. And, if you like physical media releases with a lot of bonus content, this has you covered. I cannot say that the film will appeal to everyone, but if you like campy sci-fi that is "so bad it's good", this is worth watching.
