Lindsay Lohan has cut off contact with bad influences to focus on her new film.

The 27-year-old actress has landed herself an acting and producing role in new psychological thriller 'Inconceivable' and her father, Michael Lohan, says she's cutting ties with all the bad influences in her life so that she can really focus on making the film a success.

He told the New York Daily News newspaper's Confidenti@l column: ''She [Lindsay] has Randell Emmett, who produced 'Lone Survivor' and 'Broken City', helping her. She's cut the bad friends out of her life and is taking this seriously.''

'The Canyons' actress has recently finished filming an eight-part series for Oprah Winfrey's OWN network and it's said to be an ''honest, no-holds-barred account'' of her attempt to rebuild her life and movie career after a series of struggles with substance abuse and legal troubles.

Lindsay agreed to the documentary series after completing a stint in rehab last august and is believed to have been paid $2 million for the series, despite not always showing up for scheduled filming.

A source on the 'Lindsay' production team said previously: ''She never does what she says she is going to do. She cancels all the time and is highly erratic.''

Shooting for 'Inconceivable' is set to begin next month, although no co-stars or directors have been announced so far.
