We’ll confess to being a wee bit weary of oh-so-serious Mexican director Alejandro Gonzalez Inarritu: yes, his debut ‘Amores Perros’ was fantastic, but since then he’s made film after film about spiritual despair and moral bankruptcy, and to be honest we got a bit bored. ‘Birdman’, however, sounds like a truly fascinating left-turn. Michael Keaton stars as Riggan, a washed-up actor most famous for playing a superhero (typecast much?) who struggles to regain his former fame on Broadway. With a cast including (deep breath) Emma Stone, Edward Norton, Naomi Watts, Amy Ryan, Zach Galafianakis and Andrea Riseborough, we reckon this ‘Birdman’ will turn out to be a high flyer.
