Watch the DVD and Blu-Ray editions of the Disney/Pixar movies. Not only is it easier to skip through scenes, but the disc editions of these movies provides a clearer picture than VHS or television airings so you can notice the smaller details.
Use a big screen television to watch the movie. Oftentimes the Easter eggs are small background objects and a bigger television will showcase those details a lot easier.
Play the wide-screen versions of the movies. Full-screen movies tend to cut off the picture on the left and right, also eliminating some of the hidden Easter eggs tucked onto the screen.
Access a DVD player with slow-motion capabilities. Some Easter eggs appear on the television screen for a fraction of a second and without a slow-motion DVD remote, it is almost impossible to see the hidden surprises.
Turn off the sound to the movie. The majority of Easter eggs are visual and turning off the sound will keep you away from the narrative distractions that include dialogue, music and sound effects.
Visit the movie's official page on IMDB.com. Almost every mainstream movie features a "Trivia" and "Easter Eggs" link on the left side of the page. Click on these links to find the hidden things that you may have missed while hunting for the Easter eggs.
