With no over-achieving new blockbusters to contend with, it was a good time for the smaller independent films to go out a little wider last weekend. Fox Searchlight's acclaimed teen drama Thirteen expanded by 38 into 108 sites and climbed one place to 21st on $624,611 for $1.9m in its third week. Manhattan Pictures' likeable Alan Rudolph drama The Secret Lives Of Dentists expanded by 22 to 181, climbing one to 24th and dropping 30% in its sixth week on $443,716 for $2.7m.

Strand Releasing's Party Monster grew from one to seven locations as it added $134,157 for a $161,190 running total in its second week. The Michael Alig biopic climbed 33 places to 38 and enhanced its box office take by 560% - easily the best percentage increase in the top 60.

Overall box office for the weekend was $67.4m, down 7% on the same weekend last year. Dickie Roberts: Former Child Star took the lead but grossed the lowest amount for a table topping new entry since Destination Film's Eye Of The Beholder took $5.9m in Jan 2000.

Meanwhile Universal became the first studio in history to achieve five $100m-plus summer releases as American Wedding added $2.2m for a $100.7m running total in its sixth week. The others were Bruce Almighty, 2 Fast 2 Furious, The Hulk and Seabiscuit.
