Observe and Report (2009)

As head of security at the Forest Ridge Mall, Ronnie Barnhardt (Seth Rogen) takes his job very seriously, enforcing mall rules with an iron fist. When a flasher strikes Forest Ridge, Ronnie sees a chance to display his unappreciated cop skills and bring the felon to justice, and, at the same time, impress his dream girl (Anna Faris) and win a coveted spot at the police academy.
