Eager to show off his latest work, Daniel Radcliffe attended the premiere of “Kill Your Darlings” on Saturday (January 19) in Park City, Utah.

Joking with his costars and the audience, the “Harry Potter” actor looked dapper in a button-down shirt and a brown blazer as he answered questions about his role.

As a bio-drama, the movie is based on the true story of how Lucien Carr, part of New York’s circle of the Beat Generation, murdered his stalker David Kammerer.

“Kill Your Darlings,” which also stars Elizabeth Olsen and Michael C. Hall, is slated for wider release later this year.
