I’ve worked as a contractor in the IT industry for several decades and I’ve often noted the parallels between the contracting world and the acting world. Even more so since IR35 started to affect actors and TV presenters as well as those of us in the IT industry.
As a contractor you are recruited to work on a project with other contractors and it may be for a month or a year, or longer. You become good friends working together but eventually the project comes to an end and you move on. You may meet up again with one or two of your colleagues on a future project, or you may never see them again. If you do conferences and speaking engagements you may run into someone you worked with once, or not.
With acting you are hired for a TV show or movie and you work on it until it is complete, cancelled, or your role comes to an end. You move on to other shows or movies and may run into other actors that you have worked with before, or you may never work with them again. If you do conventions you may run into other actors that you’ve worked with before, or not.
