The film is due to be released on June 27 and stars singer Leona Lewis and comedian Katy Brand.
It is a story about finding love in Italy, and has a soundtrack of hits from the 1980s.
Black Tower is releasing limited edition bottles of its Fruity White and Rosé featuring stills from the film, and running a consumer competition to win tickets to its London premiere.
The competition is one of the biggest Black Tower has ever run and will be advertised and promoted in social media.
Alex Rittlinger, marketing director for brand owner Reh Kendermann, said: “This partnership is a really exciting opportunity for Black Tower, allowing us to develop an integrated campaign that not only enables us to use on–shelf bottle promotion but also utilises our social media channels to the full.
“We are confident that the activity will be even more successful than before and will give our fans a superb chance to connect emotionally with the brand and enjoy the tunes of summer in conjunction with Black Tower.”
