Lindsay Lohan is a "troubled human," according to Scary Movie 5 writer-producer David Zucker. The 26-year-old star has the potential to be a "really good" actress if she puts her wild antics behind after completing her upcoming 90-day stint in rehab as part of her plea deal on charges of lying to police about driving during a car crash in June 2012.

Speaking at the Hollywood premiere of the new horror/comedy sequel at the ArcLight Cimenas Cinerama Dome, David told the New York Daily News, "She's a troubled human and she was late a lot to the set, but she knew her lines and she's a good actress. This seems to be the business for all these addictions and craziness. Anybody has the potential to come back and straighten out."

Lindsay arrived fashionably late to the premiere, sauntering into the cinema 30 minutes after her co-stars and muttering, "Jesus!" when she saw how many photographers were waiting to catch a glimpse of her. One of her entourage insisted, "She's really happy to be here."

The redhead - who is gearing up for her sixth trip to rehab as part of last month's court deal - turned heads in a skin-tight Dolce and Gabbana dress.

Her co-star Ashley Tisdale was all praises for the Hollywood wild child, despite not having any scenes with her in the movie: "I just know that she's a really talented actress, so I think if anything I just would love to see her do more movies. I've known her for a really long time."
