In need of proof, for the purposes of settling a costly bet, that he has one real friend in the world, a chilly businessman (Daniel Auteuil) turns to a bighearted cabbie (Dany Boon) hungry for a pal himself. And both men discover what can't be bought but can only be given and received. A premise as love-it-or-leave-it as My Best Friend's requires a sure hand to steer it safely away from the excesses of wackiness or sentiment. Delightfully, the expert Patrice Leconte (Man on the Train) produces an unlikely comedy charmer.
