Once won a close race for top spot on the per theater chart, just topping Shrek the Third $30,951 to $29,507.
Brand Upon the Brain! held up better than expected, earning an average of $18,907 in its three theaters while Chalk was the only other film to top $10,000 with $13,363.
Brand Upon the Brain! was the top dog on the per theater chart this week, scoring an impressive $46,412 in its one theater over the weekend and $63,837 since Wednesday.
In most cases this would be clear evidence that the film was destined for mainstream success. However, given the nature of the movie, it should have a successful tour of art house theaters in major cities, but it will never play in multiplexes.
The second place film was Brooklyn Rules with $41,811 an exclusive engagement ahead of this Friday's opening.
Paris, je t'aime remained in third place while its average rose to $20,247.
The overall number one film, Spider-man 3, earned an average of $13,680, which was more than the four new wide releases combined.
Finally, Waitress just maintained a $10,000 average, earning an average of $10,108 in 65 theaters.
There is little doubt the film will earn some measure of mainstream success at this point.
