* Mainly morbid curiosity, but what was Garth yelling at Wayne in the first movie during the rant that was drowned out by a landing plane? I know, RuleOfFunny, but maybe someone who reads lips can figure it out.
** Either nonsense or something that would have mostly been funny to the actors. Go on Youtube and look up what David Tennant was actually saying when the series required Martha to fast-forward a recording of the Doctor speaking, he basically just spitballed for a bit, mixing up talking about the necessity of rambling and some randomish in-character statements.

* Why do so many tropes here talking about what a Jerkass Wayne was being in the first film? he was understandably angry at losing his show and everything going wrong for him and he didnt walk out on Garth, he was FIRED and couldn't stay on the show. Yet everyone makes his slight jerkassness to Garth (who was being just as much a jerkass to Wayne) and his comment about Ben trying to "poke" Cassandra (which he was completely right about) a massive deal.
** He didn't just say that Benjamin was trying to poke Cassandra, he accused them of having actually done so already. Which is pretty jerkass, even though everything else you said is legit.

* Granted, it was the "sad" ending (and therefore not real), but if "Mr. Biggg" had no intention of signing Cassandra to a deal, why did he haul ass over to Wayne's house just to shoot her down?
