>>Kroeger's always fun to watch, strikes me as a sort of city slicker version of Robert Emhardt.>>

As the porcine manimal maker, Kroeger bears a slight resemblance to Charles Laughton -- appropriately enough given his Moreau-ish doings.  

Another fun B. K. turn is in the Batjac cheapie MAN IN THE VAULT.  As a criminal mastermind in loose-flowing sport shirts, the roly-poly character fave also gets to show a surprising amount of agility.  In one showstopping stunt (done without the benefit of a double), Kroeger takes a punch in the kisser and does an impressive back-flip over a sofa.
