The winning entry will be showcased for free in Pearl & Dean cinemas across the UK in early 2008 for four weeks.
Last year's final winner was Fallon with Sony Bravia "balls".
Advertisers can submit their entries from now until the end of January 2008, when they will be judged by a panel of seven industry experts including: Mark de Quervain, marketing director of Vue Cinemas; and Duncan Salmon, head of media planning at BSkyB.
Clare Turner, sales director at Pearl & Dean, said: "We've seen some fantastically visual adverts in 2007, many from new advertisers to the cinema.
"We wanted to give agencies the chance to showcase their TV work on the big screen, where it will gain even greater impact."
