Book-Bella's research skills are vastly inferior to those of Movie-Bella, as explained in one fun blog post. (Bella's information literacy is possibly all that improved in the transition to film!)
Here's a paper about the information-seeking behavior of characters in The Big Lebowski.
Other researching heroes (I haven't seen most of these, but I'm sure Adam has!):
- Lots of library research in Harry Potter (just how many times did they sneak into the Forbidden Section?)
- Buffy the Vampire Slayer is a classic example often mentioned in libraryland
- Supernatural is another show that frequently features research
- The movie Seven (though apparently Morgan Freeman violates patron privacy by going into circulation records...)
- Veronica Mars had a loose respect for the privacy of certain records, too, but she also used newspapers and subscription databases
- Someone uses microfilm in The Ring!
- ER characters frequently mention MEDLINE searches
