Unfortunately the UK version is not yet clear on what Audio it will carry, the US version contains: Audio: English: DTS-HD Master Audio 7.1 French: Dolby Digital 5.1 Portuguese: Dolby Digital 5.1 Spanish: Dolby Digital 5.1
Subtitles: English, English SDH, French, Spanish, Portuguese
Right now nobody except for the studio knows which languages are available on the Uk version. You will have to preorder and find out yourself or just wait until it is released. It is way too early for anyone to look into the crystal ball right now.
In fact Hugo is released in the UK by Entertainment Fim Distributors and not Paramount Pictures so the chances that this blu ray release will have any alternative languages or subtitles is quite low. Of the Blu Rays that I have that have been released by Entertainment Film Distributors none of them have any additional languages/subtitles. Hope this helps - but this film might have additional languages so maybe wait until the technical details are announced. I checked on the distributors website and they do not have any details listed for the Blu Ray release other than the date.
