Many questions regarding the different roles in the entertainment industry. Here is what i took from the Producers Guild website .    http://www.producersguild.org/?page=faq

    A Producer initiates, coordinates, supervises and controls, either on his/her own authority, or subject to the authority of an employer, all aspects of the motion-picture and/or television production process, including creative, financial, technological and administrative. A Producer is involved throughout all phases of production from inception to completion, including coordination, supervision and control of all other talents and crafts, subject to the provisions of their collective bargaining agreements and personal service contracts.

  2. What does an Executive Producer do?
    An Executive Producer supervises, either on his/her own authority (entrepreneur executive producer) or subject to the authority of an employer (employee executive producer) one or more producers in the performance of all of his/her/their producer functions on single or multiple productions. In television, an Executive Producer may also be the Creator/Writer of a series.

  3. What does an Associate Producer do?
    An Associate Producer performs one or more producer functions delegated to him/her by a producer, under the supervision of such producer.

  4. What does a Co-Producer do?
    Co-Producers are two or more functioning producers who perform jointly or cumulatively all of the producer functions as a team or group.

  5. What does a Supervising Producer do?
    A Supervising Producer supervises one or more producers in the performance of some or all of his/her/their producer functions, on single or multiple productions, either in place of, or subject to the overriding authority of an Executive Producer.

  6. What does a Segment Producer do?
    A Segment Producer produces one or more individual segments of a multi-segment production, also containing individual segments produced by others.

  7. What does a Coordinating Producer do?
    A Coordinating Producer coordinates the work of two or more individual producers working separately on single or multiple productions in order to achieve a unified end result.

  8. What does a Line Producer do?
    A Line Producer performs the Producer functions involved in supervising the physical aspects of the making of a motion picture or television production where the creative decision-making process is reserved to others, except to such extent as the Line Producer is permitted to participate. Unit Production Managers, who perform no more than the customary services of a Unit Production Manager should be credited only as such.
