Much like Tony Stark, Marvel Studios have been tinkering with Iron Man for over five years now, striving to upgrade and improve upon the previous model. In some ways, the success rate of the franchise mirrors Stark’s own cinematic journey. The first Iron Man (2008) was an unexpected hit, delighting cinemagoers whilst sowing the seeds for Marvel’s ‘Phase One’. Iron Man 2 (2010) saw both protag and film succumb to expectation, whilst Avengers Assemble (2012) took the character’s popularity to new heights. Enter Shane Black’s Iron Man 3 (2013) – a fun, action-packed superhero yarn that’s arguably Marvel’s best solo instalment to date.
