The Fault in Our Stars, a love story of two teens battling cancer, is on pace to take the top spot at the box office this weekend, raking in $8.2 million on Thursday and an expected $20-23 million on Friday. The film, which earlier this week broke pre-sales records for a romantic drama, could make over $40 million in ticket sales this weekend and has a strong shot at edging out its main competitor, Edge of Tomorrow, according to Deadline. The Fault in Our Stars is based on a best-selling novel by John Green, who probably contributed to the box office earnings when he quietly watched the film at an Indianapolis theater.
