The 30-second ad features scenes from the forthcoming Keith Lemon movie, with cameo appearances from Kelly Brook, Verne Troyer, Holly Willoughby and Fearne Cotton.
Lemon ends the promo by declaring "I'll buy a ticket for that, I will!" to tie in with the trailer's anti-piracy message.
Lionsgate will release Keith Lemon: The Film in the UK on August 24. The trailer will be showing in cinemas from today (June 8).
Nicola Pearcey, Lionsgate's managing director home entertainment and new media, said of the new trailer: "We are delighted to support the 'Moments Worth Paying For' campaign.
"Keith Lemon: The Film has outrageously hilarious antics which we're sure audiences will agree are worth paying for. And it's through their support that we're able to continue making the great films and TV shows they love."
