There aren't many eras in cinema that is more nostalgic than the period of action-adventure movies from the late seventies to early nineties. This era's films in the genre mainly come from filmmakers Steven Spielberg and George Lucas. If anyone were to list filmmakers who influenced that period in cinema the most, it would be difficult to convince anyone that they weren't the top two. Star Wars, E.T., Jurassic Park, and obviously their infamous collaboration, Indiana Jones, created an era in cinema defining the summer blockbuster.
