At least one really stupid thing in the movie....
Okay, it was a great movie, lots of fun (especially seeing Ed O'Neill/Al Bundy playing the part of a failed disco recording artist turned L.A. detective --- HAHAHA!!! lol) but I noticed they used a barely believeable movie stunt that I've seen used in one form or another in so many other movies: they had Ford throw a lit cigarette at a wet, supposedly flammable substance (in this case, a Sambuca milkshake that was splashed on somebody) and it instantly ignited into flames. Well, it's awfully hard to get things to instantly ignite when you toss a lit cigarette on them, especially something like a Sambuca milkshake. Sure, it has alcohol in it, but it is not so volatile and flammable that it would instantly ignite like that. I mean, it's hardly gasoline.
Yes, I know, it's only a movie, and lots of stuff in it was beyond belief (like when they were coming down the outside of the Capitol Records building) but I wish scripts wouldn't include the cigarette-causing-instant-fire technique. I mean, it's a Sambuca milkshake, for chrissake, not high octane gasoline! We're not all a bunch of snapperheads, you know.
