Weinstein, who worked with the Mean Girls actress on Bobby, believes Lindsay is "wonderful talent" and insists he would be happy to hire her after she leaves rehab.
When asked if her would hire Lindsay - who is currently staying at Utah's Cirque Lodge detox centre - again, Weinstein replied: "Of course. She's a wonderful actress. She did a great job in Bobby. Lindsay is a wonderful talent.
"I just hope that Lindsay is fine. She's a good lady."
The producer also believes that 21-year-old Lindsay will grow out of her problems.
He added: "You know, we keep forgetting they're kids. They're making mistakes. Hopefully, they'll clean it up and somebody will kick their butts."
Last week, Lindsay admitted she is addicted to drugs and alcohol.
The actress admitted she is "ashamed" of her recent behaviour and accepts she is out of control.
She said: "It is clear to me that my life has become completely unmanageable because I am addicted to alcohol and drugs. Recently, I relapsed and did things for which I am ashamed."
The star made the statement shortly after reaching a plea deal for two counts of DUI (driving under the influence), two counts of being under the influence of a controlled substance and a reckless driving charge.
