Sorry for the delay, but I've been out of the office.
You are using the term "penalty," which legally means a fine payable to the government or court. I don't think this is necessarily what you mean. That said, each Labor Code violation subjects the employer to a $50 penalty for the first violation, and a $100 penalty for each subsequent violation. Labor Code § 1199.
However, there is no penalty for working more than 5 days per week in the motion picture/television industry. The employee is simply entitled to overtime for the additional hours.
If what you mean is how much overtime is the employee entitled to, and that the film crew has elected an "alternative work schedule," pursuant to IWC Order 12-2001
(3)(B), then: "All work performed in any workday beyond the schedule established by the agreement up to 12 hours a day or beyond 40 hours per week shall be paid at one and one-half (1 1/2) times the employee’s regular rate of pay. All work performed in excess of 12 hours per day and any work in excess of eight (8) hours on those days worked beyond the regularly scheduled number of workdays established by the alternative workweek agreement shall be paid at double the employee’s regular rate of pay."
Note: If I've misunderstood your question, then feel free to clarify.
