The Definitive 'Time Bandits'!
Amazing video and audio quality. Details and textures abound. The gold in the movie actually looks like shimmering gold.

Great version, Love the packaging, Video quality is not perfect.
Really nice transfer considering the year this was made. I'm not sure if this could be cleaned up video signal wise any more than it is, because I'm not sure the source. But loved seeing the movie again, and it looks really good on my 138" projected image. Love the packaging.

4K Remaster Quality
I received the 4K / Blu-ray today 06/13 and l am very critical of video and audio quality. I'm not going to review the film but it is excellent with all the Monty Python influences and the iconic stars in the film! But just to assure everyone, the quality of these Criterion discs are perfect! I've never seen this film like this before, if you buy this one, you will not be sorry! The 4K disc also comes with a Blu-ray of the film. Just to mention, the George Harrison song at the end "Dream Away" is also outstanding! 5 Stars!

I'm a huge Time Bandits fan, and I wasn't disappointed
I saw this in the theater (I'm old) and a bunch of times on VHS, DVD and on TV. But nothing beats the movie in super-clear 4K, great sound and CLOSED CAPTIONING.

Epic
When it comes to 80s fantasy movies, the words that often come to mind are creative, dark, weird, and original. Time Bandits is the epitome of great 80s fantasy, especially the dark and weird part. A huge inspiration for my personal writing, Time Bandits is an epic film with some of the most creative and original imagery you will ever see in your lifetime. I had to own this in 4K UHD; it's just too special a movie for me. Spoiler: I still can't believe that scene with the exploding microwave.
