After the untimely death of Michael Jackson just over 2 years ago, the Disney Theme Parks reintroduced the classic Captain E.O. 3D film and attraction back into their parks (almost) world wide.
Disneyland Paris was no exception, especially as the guests who visit that park really have a soft spot for retro and classic Disney attractions. The film returned to Discoveryland on June 12th 2010, taking over the old Honey I Shrunk the Audience attraction (which, in my opinion, was starting to become more outdated and less 'retro').
