The Last Exorcism should end up in the low 20s, which still will make it only the 17th $20m opener in Lionsgate history. It's starting out just a little behind the company's The Haunting in Connecticut, which creepy-advertised its way to a $23m start in March of last year. Ironically, they are using Eli Roth's name to open this film to more than any Eli Roth movie has ever opened.
