Eli Roth Made it . / directed it
But Tarentino Produced it .and by produced it i dont mean the way most holloy wood movies are produced ..
. What he does since he is a well known director isnt really anything but Mention It ,
Thats it he did the same thing for The Protector
Instead of Producing ,, think of it as endorsing ,,
From Wiki
In recent years, Tarantino has used his Hollywood power to give smaller and foreign films arguably more attention than they would otherwise have received. These films are usually labeled "Presented by Quentin Tarantino" or "Quentin Tarantino Presents". The first of these productions was in 2001 with the Hong Kong martial arts film Iron Monkey which made over $14 million in the United States, seven times its budget. In 2004 he brought the Chinese martial arts film Hero to U.S. shores. It ended up having a #1 opening at the box office and making $53.5 million. In 2006, the latest "Quentin Tarantino presents" production, Hostel, opened at #1 at the box office with a $20.1 million opening weekend, good for 8th all time in January. He presented 2006's The Protector, and is a producer of the (2007) film Hostel: Part II. in 2008 he produced the Larry Bishop helmed Hell Ride, a revenge biker film.
The reason why he did it is probably because him and Eli are very good friends... Eli is actually in tarentinos new flick Inglourious Bastereds ,, as the " bear jjew "
