9 Times Actors Majorly Spoiled Their Own Movies
7. Sylvester Stallone - Creed

2015 saw the highly anticipated release of the next instalment in the Rocky film series, starring Michael B Jordan as Adonis Creed, son to previous Rocky boxing champion who wishes to follow in his father's footsteps after his tragic death in Rocky 4. Sylvester Stallone reprised his own role as the famous protagonist now retired Rocky Balboa as mentor to the young boxer.
Ten years on from the last movie in the Rocky franchise, fans highly anticipated and waited for the movie to be released, with little news allowed to be let out about the plot. Unlucky for the production company, Stallone had other plans.
Posting what he thought was an innocent picture of the screenwriter's meet up before production began on to his own Instagram, Stallone framed in a piece of the script on the table along with some of his own notes attached. The script page was upside down, but viewers soon managed to work out the action happening on the page and gave away the ending scene.
Along with this, in 2017, for Creed 2, Stallone leaked the return for Rocky arch enemy Ivan Dranko after posting his own script notes in a notebook - get that man off Instagram!
