OK, it's not for the premier, but this week's Radio Times (16-22 April) is giving away PAIRS of free tickets for preview showings on the morning of Sunday the 24th April. First come first served and it doesn't say how many pairs they have for each venue but you collect them in person from the participating cinema.

Full list of the places on page 10 of the RT and you have to take the voucher to the right cinema in:
Belfast, Birmingham, Bracknell, Brighton, Bristol, Cardiff, Edinburgh, Glasgow, Liverpool, London W2, Manchester, Newcastle, Norwich, Nottingham, Sheffield.
