Christopher Nolan's Interstellar is reportedly projected to bring in more than $50 million over its opening weekend. According to Variety, early tracking suggests that Interstellar will score big at the box office opening weekend, with analysts speculating it may be in the same range as Gravity's $55.8 million opening weekend. These numbers would represent an impressive opening for the space adventure, which reportedly came in $10 million under its $175 budget. Tickets are already selling out in many of the major theaters, and some IMAX theaters have added 3:30 and 8:00 a.m.
