The Exchange is pitched as a film by Borat co-writer Dan Mazer.  The ad campaign conveniently omits Mazer’s more recent effort Dirty Grandpa, a hard-R gross-out comedy that was dragged by critics and audiences alike although I feel like those reactions were over-the-top and unnecessary.  This exclusion, though, may not be because of Dirty Grandpa’s negative reception, but because The Exchange has more in common with Borat – to an extent.
