A producer on Mischa Barton's new flick "Homecoming" isn't thrilled she missed the NYC premiere after being involuntarily checked into a psych ward Wednesday. (Additionally, "Access Hollywood" is reporting that Barton is in the hospital under an involuntary 72-hour psychiatric hold.)

"It's frustrating. And it's not ideal," Bingo Gubelmann told at the Thursday premiere. "It's frustrating, but I'm not going to sit here and trash her because we're young as a company and we've got to live and learn...I don't want to be known as the producer that will turn on any actress at the drop of that hat."

While rolling his eyes, Gubelmann continued that "it's hard to remember" why he chose Barton to star in his indie flick, "because, you know, she's not here right now.

"Now, I haven't spoken to her yet because she's totally unreachable, so I don't know exactly what happened. I mean, I'm not as good at taking the high road as some people and yes, it would obviously be nice if she was here. Even just to hang out," he went on.

Gubelmann said Barton didn't seem "at all" unstable while shooting the flick in less than a month, 16 hours a day.

"She did it and she did an amazing job. It's like, maybe she went Method and maybe that's what happened!" he said, laughing.

Producer Austin Stark was more sympathetic toward the actress, who required a police escort from her Hollywood Hills home to the hospital.

"I think we would have loved to have had her come out and support the movie, [but] you know, we wish her the best and obviously we hope she gets better," he told Us. "Obviously, it's a trying time for her. I mean, obviously we'd like her to be here but I don't think it hurts the movie."

Added producer Benji Cohen: "She's going through a rough patch and she can't be here. And it's really too bad."

Director Morgan J. Freeman told Us: "I hope Mischa is doing OK. My thoughts and prayers are with her. Health first, movie second."
