Osborne drew inspiration from his personal life and failing marriage with Pamela Lane while writing "Look Back in Anger", which was his first successful outing as a playwright. The play spawned the term "angry young men" to describe Osborne and those of his generation who employed the harshness of realism in the theatre in contrast to the more escapist theatre that characterised the previous generation. This harsh realism has led to "Look Back in Anger" being considered one of the first examples of kitchen sink drama in theatre.
