UNTOUCHABLE (15, 112 mins) *** Starring Francois Cluzet, Omar Sy, Anne Le Ny, Alba Gaia Kraghede Bellugi, Audrey Fleurot, Clotilde Mollet, Gregoire Oestermann. Directors: Eric Toledano, Olivier Nakache

Loosely based on a true story, this crowd-pleasing comedy has smashed box office records in France and charmed audiences around Europe.

An English-language remake, reportedly starring Colin Firth with director Paul Feig (Bridesmaids) at the helm, is already in the works, attesting to the film’s potential as a dark horse at next year’s Oscars.

Dubbed by some wags as Driving Monsieur Daisy, this feelgood confection centres on the culture clash between a wealthy white aristocrat and a street-smart Senegalese ex-con.

Untouchable boasts some uproarious interludes, including a badly-behaved night at the opera, and the film is anchored by a stellar performance from Omar Sy as the jailbird, who teaches his stuffy employer to loosen up by trading Vivaldi for Earth, Wind & Fire.

However, for all its endearing qualities – and there are many – the picture trades heavily in racial stereotypes, and when the laughter subsides, you’re left to contemplate whether the writer-directors are guilty of crude insensitivity or flagrant racism.

I’m willing to give them the benefit of the doubt; others will be less charitable and forgiving.

Philippe (Cluzet) is a wealthy aristocrat who suffers terrible injuries in a paragliding accident.

He roams his sprawling Parisian mansion in a wheelchair and requires constant care to accomplish everyday tasks.

In an opening montage, a series of eminently-qualified carers apply for a position in Philippe’s household, but he is unmoved by their glib answers.

Uncouth ex-con Driss (Sy), who has only applied for the job to get a signature on his benefits card, is a breath of fresh air.

He flirts outrageously with Philippe’s prim secretary, Magalie (Fleurot), and dares to steal a Faberge egg from the hallway.

Attracted to Driss’s complete lack of pity, Philippe hires the most unlikely candidate as his live-in carer.

The former jailbird takes up residence in an opulent guest room and quickly clashes with personal assistant Yvonne (Le Ny).

Against the odds, Driss forges a tender bond across the class divide, helping Philippe to teach his brattish daughter Elisa (Bellugi) some manners.

Untouchable rests heavily on the shoulders of Cluzet and Sy, whose winning screen chemistry atones for the script’s occasional crassness.

They share some lovely scenes.

The buddy comedy provides lots of small emotional peaks, but at the very moment you expect Untouchable to deliver a big wallop, the film opts for a smaller pay-off.

The reluctance to indulge in shameless sentimentality, which distinguishes the film, also diminishes it.
