Imagine being in a situation where you had to choose between attending an Ivy League school or starring in a movie with Jennifer Lawrence. You really are between a rock and a hard place, like the expression goes. Andrew Barth Feldman, who co-starred with the Oscar winner in the R-rated raunchy comedy "No Hard Feelings," had to choose between taking part in this movie or continuing his studies at Harvard. And Lawrence had her own way of helping him make a decision.

Jennifer Lawrence can sell people on just about any project she does. So it shouldn’t come as too much of a shock that she was able to do the same when it came to Andrew Barth Feldman. ET spoke to the 32-year-old actress at the New York Premiere of their new movie about how she helped Feldman decide. Apparently, the witty star used placed an A+ phone call to sink Feldman, who she thought was perfect for the role of Percy.
