From one of my favorite blogs, ResearchBuzz! , I found out about a new feature from the Internet Movie Database—Movie Keywords Analyzer (MoKA) .
You can find titles that have a particular keyword and get a tally of all keywords from the titles that matched your initial keyword set.
I searched "tomatoes" because I was thinking of the funny sci fi parody I saw years ago and these are the matches I got. Attack of the Killer Tomatoes! was among them.
tomato (41 titles - Jonah: A VeggieTales Movie (2002), ...)
mashed-potatoes (2 titles - Close Encounters of the Third Kind (1977), ...)
giant-tomato (1 title - Attack of the Killer Tomatoes! (1978))
stuffed-tomato (1 title - Penny Wisdom (1937))
comatose (6 titles - "Carnivàle" (2003), ...)
automat-restaurant (1 title - That Touch of Mink (1962))
marcantonatos (1 title - Wannabees (2002))
