'Inferno' director defends Lindsay Lohan

Says shooting will begin as scheduled Nov. 15.

Lindsay Lohan admitted on Twitter she failed a drug test, but the producer and director of "Inferno" are standing by her side.

"Did this throw us for a U-turn? Sure," director Matt Wilder told People.com. "But no one has conveyed any pissiness about it."

Wilder says shooting is still set to start Nov. 15 in New Orleans, depending on what Judge Elden Fox rules after meeting with Lohan this week. She may face 30 days in jail.

The director says he was touched by Lohan's honesty on Twitter.

"This is not something to be pissed about," he told People. "If someone fails a drug test but says I am trying hard and struggling, it's hard for me to be angry."

A report surfaced over the weekend that the producers were "beyond irritated" that Lohan, who plays porn star Linda Lovelace in the biopic, had relapsed.

"The only producers in question would be Jordan Gertner or myself, and we are not expressing irritation, nor ' beyond irritated' to anyone -- that is not to say we would not be upset over a breach of the court by Lindsay that has affected her personally, or the potential production schedule or location of the production significantly," producer Chris Hanley told People.

"We are way not happy to not be making this movie this year as planned, and if the ability to shoot in a film incentive program state is not available due to travel limitation placed on Lindsay, that would be a concern, but that cannot be addressed until it is known," he continued.

"We do believe that Lindsay's talent does weigh very heavily in this matter. Addictive personality disorder issues are pervasive in the film industry. I have worked with Robert Downey and others on movies I have made, and, frankly, talent and passion for a project matter the most to me."
