Ask the director of the Peter Pan stage production to decide if Tinkerbell should be portrayed using a followspot or laser pointer. Traditionally, a followspot is used; however, modern productions sometimes utilize a laser.
Ensure the theater has the appropriate number of followspots for the production. An additional followspot may need to be rented. If the director chose to use the laser, you can find these through theatrical lighting suppliers, amateur astronomer/telescope stores and many electronics stores.
Attend technical rehearsals of the play, per the director's request, to learn Tinkerbell's blocking and cues. The director will tell you when the light should appear and where the light or laser should be focused. If using a followspot, you may be asked to tightly or loosely focus the spot based upon Tinkerbell's movements. The musical director or sound operator may also be asked to ring bells or play notes on a keyboard or piano to represent Tinkerbell's dialog or flight.
Practice Tinkerbell's cues and blocking. It can be difficult for a non-seasoned followspot operator to aim the spot light exactly where Tinkerbell is supposed to be.
Perform Tinkerbell as directed during each show. Following a preview performance, and sometimes after a regular performance, the director may give you additional directions or notes on how the performance can be improved.
