Sure, it has received a critical mauling, and the movie-going majority are avoiding it like the plague. But with a budget reported to be around $10 million, and an opening of $11 million, the movie is already set to make a profit, and on that basis can be considered (moderately) successful. To put it into a bit of perspective, I think it is important to point out that Skyline’s opening weekend total earnings matches almost exactly that of another much maligned alien invasion movie. The difference is that 2000′s Battlefield Earth cost a staggering $73 million to make, resulting in a $50 million loss. When all is said and done, Skyline could almost double it’s money. So what can we learn from the story of Skylines’s ‘success’?
