 An alternate version of the Nick Fury post-credits scene was filmed in which he specifically said "As if gamma accidents, radioactive bugs and assorted mutants weren't enough" referencing Hulk, Spider-Man and the X-Men but this was cut due to legal problems with Sony Pictures and 20th Century Fox who at the time had full ownership of the characters until their reacquisition much later in the mid to late 2010s.Favreau's main concern with the film's effects was whether the transition between the computer-generated and practical costumes would be too obvious.He hired Industrial Light & Magic (ILM) to create the bulk of the visual effects for the film after seeing "" and "Transformers".
