The comedy, starring Queen Latifah and supermodel Gisele Bundchen, will be promoted via a takeover of the Monkeyslum homepage with the yellow branding of a New York taxi.
The deal includes banner ads on Monkeyslum.com, editorial links to the official film site via the competition section, and editorial in HTML newsletters to be sent to its email database.
Users can view the film trailer and read content, and then click through to the official web site (www.taximovie.co.uk) to book tickets and register for details.
The film will also be promoted via takeovers on malefirst.co.uk and funky.co.uk.
Creative was by online marketing and design agency JAM, which specialises in film promos.
Daniel Robey, Jam managing director, explained: "The strategic approach taken on this campaign through our online PR, promotional and creative offerings places Taxi in the perfect position to target its key audience online."
Monkeyslum targets boys of 11 to 19 with football, girls and gadget content.
It claimed six million page impressions and 250,000 unique users in the first month of its launch.
The deal is Monkeyslum's first film promotion since it launched in September (see Revolution, September, p71).
