The studio included the following provisions in the first draft contract that they sent to you:

1. Promotional and Publicity Services. Artist shall render all services (Promotional Services) required by Studio, as, where and when required by Studio (both during production of the Picture and in connection with the initial theatrical and video release of the Picture), in connection with the publicity and promotion of the Picture, including without limitation attending premieres of the Picture, making appearances at press conferences or on television, making personal appearances, engaging in interviews, participating in photo sessions, cooperating in the photography of behind-the-scenes footage and participating in promotional tours and press junkets. No additional compensation or other remuneration shall be payable to Artist with respect to the Promotional Services.
2. Credit. Provided that Artist appears recognizably in the role for which he was engaged, Artist shall be accorded on-screen credit on the Picture if the Screen Actors Guild Agreement (SAG Agreement) so requires. All other matters relating to Artist's credit, including size, position, and placement shall be at Studio's discretion.
3. Merchandise. Studio shall have the unrestricted right to utilized Artist's name, voice, and/or likeness in merchandising items related to the Picture, provided that Studio will not use Artist's image in connection with the sale of tobacco products without Artist's consent.

Select one of the three clauses presented and revise it in a manner that would be more beneficial to your client, but that you believe the studio might also be able to live with.
