I can't tell if the trailer is false advertisement to reach a bigger audience, or if it was done on purpose to surprise the viewer, but either way, this movie is far from a comedy and is hands down a drama with even a few metaphorical tid-bits and some film noir influences.
Plot: Howard Holloway(Clark Gregg, mostly known for his role as Agent Phil Coulson in S.H.I.E.L.D., Avenger etc.) is a former child star who, after his career went down, started his own agency to represent child stars of his own. Business is running slow and to make things worse, his most promising clients are getting poached by his "arch enemy" Aldo (Sam Rockwell). His love life is not doing well either, as his approaches on his crush and neighbour Marcy(Amanda Peet) are not leading anywhere either. This all seems to change abruptly when he manages to land a promising new actress, named Lydia(Saxon Sharbino), without his doing to be honest.
What does start off and sound like a "stereotypical" underdog hits big comedy plot couldn't be farther away from that.
Clark Gregg (who also wrote and directed Trust Me) is taking you on a ride that starts as a mild comedy with some shades of drama and step by step turns it into a fully fledged drama that will leave you surprised.
The acting throughout the whole movie is solid and really lives off the great chemistry between the actors. Especially Saxon Sharbino is standing out with her great performance that will go from childly innocent to devastated to treacherous in a heartbeat.
I can't stretch this enough, but don't expect to end the movie with a smile or laughter. It really is not a comedy. The movie even has a few metaphorical tid-bits that don't really stand out at first, but at the end you get what they were supposed to mean. And on top of that the movie even has a few film noir moments that don't seem to fit at all if you got the trailer in mind, but they are scarcely spread in the movie and really fit the mood.
Overall I can definitely recommend this movie.
