"My work is distinct and definitive and specific and hopefully it is so that every single character is different, and they are but -- there's probably an underlying element that's me," Keaton told ET in 1987.
In Birdman, Keaton plays a washed-up actor by the name of Riggan Thompson who once played the superhero Birdman in movies, but he must overcome his family troubles in an attempt to reinvent his career on Broadway.
The role, while bold and new for the actor, could easily be seen as an homage to his own portrayal of Bruce Wayne in Batman Returns. There is certainly an element that is very Keaton.
