Gordon-Levitt wants Moore for debut
Julianne Moore could be playing for laughs in Joseph Gordon-Levitt's untitled directorial debut.
The Oscar-nominated star is apparently in talks to take a role in the upcoming film, which Joseph wrote and will also star in, reported Variety.
The 51-year-old is expected to play an unlikely mentor to Joseph's character - a modern-day Don Juan who sets out on a quest to become a nicer person.
Scarlett Johansson is also on board to co-star.
Joseph, who has been directing short films for years, has cited his experiences with acclaimed filmmakers such as Christopher Nolan, Rian Johnson and Steven Spielberg as his inspiration.
Julianne - who portrayed former Alaskan governor Sarah Palin in TV movie Game Change - next stars in fantasy epic Seventh Son opposite Jeff Bridges. She's also a contender to play the unhinged religious fanatic mother in the Carrie remake with Chloe Moretz.
