Mission: Impossible 2 (2000)

Continuity mistake: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tyres to road slicks, back and forth depending on what terrain they were on. Easiest to see when Ethan skids on the road to avoid the white van - clear shot of slick tyres - then about 30 seconds later they're on the dirt, he skids into the old car and you can easily see that he's got off-road tyres front and back.

Ethan Hunt: You turned around.
Nyah Nordoff-Hall: What are you going to do? Spank me?

Trivia: The delays on the MI:2 shoot cost two of the actors high profile roles: Dougray Scott was replaced by Hugh Jackman in X-Men, and Thandie Newton was set to play Lucy Liu's role in Charlie's Angels, but this shoot ran so long that she didn't want to commit to another 6 month shoot immediately, so pulled out.

Question: Why didn't Ethan just give Nyah one of his guns after she infected herself? She could have easily killed Ambrose and others with a surprise attack since they were more interested in keeping her alive and she wanted Ethan to kill her anyway. She had better odds of surviving that way than the impossible plot that followed. She could have killed everyone but Ambrose and he may have let it happen in order to still have a chance at selling the virus.
