What is the longest bluray movie ever made on one disc?

The "extended edition" of Once Upon A Time In America (249m), which was released in Italy, is/was one disc. To the best of my knowledge, nothing else anywhere near that length has been released on less than two discs.

EDIT: I done goofed--Kenneth Branagh's 1996 adaptation of Hamlet (242m) is also on only one disc. (And to answer the other previous question: AFAIK, the existing Cleopatra BD is two discs. It looks like the upcoming Region A release is two discs as well.)

I'll apologise in advance for a very tiny derailment.

I ripped my Blu-ray Disc of Bonnie and Clyde with only the English language track and no subtitles (just the film, no extras).

I seem to remember it coming in at about 16Gb, so you could probably fit it 3 times on the disc.

Bonnie & Clyde has a running time of 112 minutes, so that would work out to 336 minutes (over five and a half hours).

It looks great, too!

Lawrence of Arabia is 227 minutes on a single disc and the image and sound is absolutely perfect so no issues with fairly long movies on a single disc.

Gods and Generals: Extended Director's Cut is 280 minutes on a single disc and Gettysburg: Director's Cut is 271 minutes on a single disc. Those are the two longest single-disc Blu-Rays that I know of.

Hey Lex. I went to school at W&L and have Gods and Generals on DVD. Love the place.

I take it any extras were on a second disc?

The television/extended version of Fanny & Alexander is 322 minutes on a BD50. Judging by some reviews, Criterion was a little too ambitious in trying to fit the almost 5 1/2 hour feature onto one disk.

I believe the difference in PQ between the two versions is entirely due to being from different sources, rather than the bitrate.
