The HULK

Then of course Dad #2 goes and blows the living crap out of him with a nuke, as they so often do in Hollywood scripts

Yep, a Large Fuel Air Explosive munition would be a simpler and quite effective weapon to get rid of a huge gas bag. Using nukes? Uh, not bloody likely, but then, Hollywood likes to prey on the primal fear of nuclear weapons wherever possible, like in the movie "The Peacemaker."

Also, the fact that tactical nukes were removed from the inventory in 1991 seems to get overlooked, but then, this is Hollywood, as you so rightly point out, and when you consider what they do with 'history' it is no surprise what they do with 'future' and 'present.'
