However, total box office was up 15.5% from the same period last year because of the rise in the average ticket price from $2.65 to $3.25.
Hollywood blockbusters took an 84.8% share of the market (87.8% in the same period of 2006), local productions logged 4.4% (from last year's 4.1%), while European, Asian and other Latin American films recorded a 10.8% share (up from 8.1% a year ago).
The fall in admissions particularly affected Argentinian films. The 38 titles, including co-productions, released during the first six months sold only 800.000 tickets. Juan Taratuto's romantic comedy Quien Dice Que Es Facil (Who Says It's Easy) was the best performer, but that was only good enough for the tenth spot in the overall top 10 with 420,000 tickets.
Only four American films have attracted over one million viewers, led by Pirates of the Caribbean: At World's End with 1.555m and counting.
Germany's The Lives of Others (290,000 tickets sold) and the UK's The Queen (270,000) were the most successful European productions of the Jan-June period.
The local industry is still confident that it will beat last year's 11.6% share, thanks to several upcoming high-profile local releases as Rodolfo Ledo's police comedy Incorrigibles and two animated features - Jose Luis Massa's Isidoro and Juan Pablo Buscarini's The Ark - all set for the winter holidays this month, which is traditionally the most profitable period of the year in the country.
