The Marvel Cinematic Universe has become the definitive franchise for all things Marvel. However, even though the franchise began in 2008, there were many movies based on these characters released in the decades prior. The early 2000s specifically featured some of Marvel's most famous characters, such as the X-Men, Spider-Man and the Hulk. But 2003's Daredevil introduced one character that many never thought to see again -- Jennifer Garner's Elektra.
