Anyway, 14 years ago, Tony Stark tells Mike from Neighbours to meet him on the roof in twenty minutes and decides to blow him out and shag some woman who collects exploding plants instead.
After waiting for a while on the roof, Mike realises that Stark isn't coming and decides that'll he'll get his revenge by turning into an angry glow-worm, buying a nice house for Ben Kingsley and blowing people up with his army of glow-bombs.
Too long, plot holes you could reverse Denmark into and too much CGI. However, as (I assume) this film's mostly made for kids, it's one of the better enormo-budget efforts. First Iron Man's by far the best though.
Also, I kid you not, Croydon is mentioned.
Me and my brother saw it in Croydon. It was a magic, Croydon-y moment.
