Well, this is another good question...
Roland Emmerich (just know him by name...) has sometimes proved his abilities being a director.
John Woo... never heard that name before...
And producing movies along with Sylvester Stallone is moreover the fame. Casting a few actors for boxing event for example... training together...
all other movies were partly "conservative". Sly was always the one kicking buds and the rest, just usual and there to full fill the movie set, had no good activities.
Not quite sure yet... ^^
