So… there are Easter eggs in movies? Not exactly. Though sometimes there are. “Easter egg” is an industry term suggesting hidden tributes, props, art design, random characters and the like which are placed into the mix for story depth, but most often as an homage to another film, friend, mentor or filmmaker in the business. Yes, in Rocky Horror Picture Show, the cast actually hid eggs in various places that can be seen throughout the film, but the following “Easter eggs” are a lot more intentional, and very cool when you catch them.
12. Star Trek – R2-D2
Was J.J. Abrams sending a little message to the fine folks at LucasFilm about wanting to helm the next Star Wars? Most likely, it was just a nod to one of J.J.’s favorite franchises, and one of his greatest inspirations. What was it, you ask? In the 2009 version of Star Trek, audience members can catch a glimpse of R2-D2 zip by the main control room in Starship Enterprise with a bunch of space junk, as the ship approaches a Romulan vessel. There’s never been any secret about J.J.’s love for Star Wars, so it was likely just an homage; however, there’s a strong argument that he had already enjoyed a couple conversations about taking the helm of The Force Awakens.Source: Gizmodo
