Most overt product placement in movies
I left The Invisible Man yesterday any my friend turned to me and said: "Was that just one long commercial for Nike?" and, yeah, I kinda hadn't consciously noticed, but there were a fair few close-ups of footwear in the movie.
I also saw 90s slasher pic Urban Legend last week and there was an awful lot of Pepsi to be seen floating around, which reminded me of "Fuller! Go easy on the Pepsi!" in Home Alone, which changed to Coke in Home Alone 2.
What are some other films with really obvious product pushes?
