According to Channel 4 it will be the first time a UK broadcaster has broadcast an entire break of non-English language ads.
The premium break was collaboratively devised and managed by Channel 4 Sales, working with media agencies ZenithOptimedia, acting for L'Oreal; Manning Gottlieb OMD for Renault; OMD for Bel Boursin, and Starcom for Emirates.
The one-off break will last three minutes and 30 seconds. It will be broadcast during the first ad break of 'The Returned' at approximately 9.10pm on Sunday 9 June and will be introduced by a French voiceover, which will also carry subtitles.
The creative agencies behind the ads in the themed break are McCann London for L'Oreal, Publicis for Renault, Rainey Kelly Campbell Roalfe/Y&R for Bel Boursin.
A spokeswoman for Channel 4 could not confirm the ad agency behind the Emirates ad by the time of publication.
Jonathan Allan, the sales director at Channel 4, said: "We're really excited to bring the first entirely French ad break to Channel 4 to herald the arrival of our eagerly awaited new zombie drama series – it should really make the ads fit within the context of the show and surprise the viewer, cutting through to the audience.
"This themed spot is a great example of how Channel 4 is able to deliver its advertising partners innovative marketing solutions, by creating an event to attract and engage audiences with our clients' brands."
Channel 4 acquired the UK premiere broadcast rights for the 'The Returned', from Zodiak Rights.
