I’d like to think that these are two of Nick Fury’s missions before he joined SHIELD. The first being an undercover mission with NYPD officer John McClane in New York City. That’s how he knows Manhattan so well. It was from McClane that Fury got his smart-assed remarks. The second mission, where Fury worked as a software technician at Jurassic Park. It was here that a dinosaur got loose. This is also where Fury developed a fear of big green monsters, hence Bruce’s “cell” on SHIELD’s helicarrier. Case Closed.
