According to inside source at Vulture, I Am Number Four actor Alex Pettyfer, may be ditching one young-adult franchise for another.

It seems talks between Screen Gems and reps for Alex Pettyfer have reached an impasse, and the young Brit won't be starring in the studio's adaptation of Cassandra Clare's best-selling young-adult books, The Mortal Instruments. Instead, the young seems to have opted to the lead role in Warner Bros. and Legendary Pictures' adaptation of Joseph Delaney's best-selling YA series The Last Apprentice (known to U.K. readers as The Wardstone Chronicles), about a teenage boy training to be an exorcist in the 1700s.

"The project is heating up fast, our spies say, with Oscar nominees Jeff Bridges and Jennifer Lawrence possibly playing roles as well; Bridges is being offered the part of the exorcist to whom Pettyfer would be apprenticed, and Lawrence that of a suspected witch."
