Pringles consumers will get the chance to take eight people to a Hollywood celebrity screening of the final film in the Lord of the Rings trilogy, The Return of the King, in an on-pack competition.

Promotional 200g cans in the brand’s top five flavours will be on shelf from the middle of next month.

Only one contains the winning ring but there are thousands of other prizes on offer, including a home theatre gaming system, videogames, DVDs and videos.

Each can carries a code which consumers enter into a website.
