29 C.F.R. § 541.709

The requirement that the employee be paid “on a salary basis” does not apply to an employee in the motion picture producing industry who is compensated at a base rate of at least $1,043 per week (exclusive of board, lodging, or other facilities). Thus, an employee in this industry who is otherwise exempt under subparts B, C, or D of this part, and who is employed at a base rate of at least the applicable current minimum amount a week is exempt if paid a proportionate amount (based on a week of not more than 6 days) for any week in which the employee does not work a full workweek for any reason. Moreover, an otherwise exempt employee in this industry qualifies for exemption if the employee is employed at a daily rate under the following circumstances:

(a) The employee is in a job category for which a weekly base rate is not provided and the daily base rate would yield at least the minimum weekly amount if 6 days were worked; or

(b) The employee is in a job category having the minimum weekly base rate and the daily base rate is at least one-sixth of such weekly base rate.
