Whilst there's been advanced screenings all over the place, Marvel has opted out of showing the post-credits scene for "Guardians of the Galaxy" - saying they plan to keep the surprise under wraps until the general release. With the movie about to hit cinemas in the next day or so, it appears as if a bootleg copy of the post-credits sequence may have leaked online and is doing the rounds. SPOILERS AHEAD The scene, which briefly appeared over at Vulture before being yanked, is essentially a one-off joke.
