The “brothers who couldn’t be more different” scheme falls apart if they’re wildly unalike — sired from wholly separate gene pools. I can see the markedly dissimilar Roy Scheider and Dustin Hoffman being brothers in John Schlesinger‘s Marathon Man (’76) but not Mark Strong and Sacha Baron Cohen in The Brothers Grimsby. Call me a literalist without a sense of humor but all good comedies are made of the same stuff that goes into good drama, including occasional echoes of the world as it actually is. Worse: SBC having sex with a fat girlfriend in a mattress showroom.
