Well, first you would have to get a Blu-ray drive that connects to your Mac or PC. Macs don't have a Blu-ray drive. Most PCs don't either.
Then, you would need to use a piece of software that "rips" the video to a file format supported by the iPhone. Handbrake does that for DVDs, and I think it does it for Blu-ray too if you have the right hardware and set it up right. There might be other software apps that do it too.
Then you would end up with a file that could be synced to your iPhone via iTunes.
Of course the iPhone screen is considerably smaller than the 1920x1080 of Blu-ray. So if you have the DVD, you might as well rip that instead. Or, save the money it would cost to get the external Blu-ray player and just rent the movie on iTunes.
