Variety has an excellent post titled “Billboards in LA: Old School Method Still Gets Results in Busy City”. The movie theater industry spends approximately $250,000 per movie on billboards in LA.   Insider was stunned by the prices the boards command:

• Burbank $3,500-6,500/month

• Studio City $4,500-7,500/month

• Century City $6,500-10,000/month

• West Hollywood $10,000-25,000/month

• Beverly Hills $8,500-25,000/month

Dramas and kids movies are best suited for billboards.  They have simple or powerful themes which come across well in a single message.  Comedies have subtler messages which can be harder to get across.
