Cheers, that seems to back up what I'd found through looking at a few of the likely suspects and not seeing it on. Surprised nowhere has taken the option of showing it again or a double bill.
I think some of the Picturehouses had been showing it on the run up. Know a colleague did a double header on Thursday night/Friday morning at one of them.
I don't think it is.
If you Google for "London Film Times" it gives a pretty exhaustive list and there is no Dune One on it.
