POST production FILM publicity expenses tax deduction
Hi, I have a friend who is a film producer. He completed production of a film in early 2007. In 2008 he spent money in looking for a distributor. He found a distributor in 2008 and released his film in theater in 2008. So for 2008 he has income from film distribution. At the same time he spent money in 2008 in advertising/publicity/marketing of the film. My question is
What is IRS rule for deduction of film advertising/publicity/marketing expenses?
I would appreciate citation of any specific section or publication.
Note: I believe it may be a normal business expenditure that can be deducted. But I may be wrong and also I am looking for specific provision.
Note: I am aware of section 181 that talks about film production cost but what I need is about film post production cost.
Thanks for help
