Pros
I've worked on and off for Moving Colour many times for the past 4 years, and have since worked at both big and small studios. The work I did at MC is still some of the most creatively satisfying work I've done. Brian does a great job of making sure a project fits all client needs, while also satisfying the creative appetite of his employees, which makes it a win for all. It becomes clear that there's a reason clients like Disney, Target, Spotify, and many other well renowned names trust him to do big jobs for them. As a freelancer, you will end up wearing many hats, which personally I found to be an opportunity to strengthen and explore different skillsets, and helped lead me to other work. A lot of freelancers come and go as jobs require them. I found this great for networking, and it always brings new creative ideas and energy to each job. I should note that I personally witnessed significant diversity in these hires, greater than what I've seen in much of the industry. Brian usually just chose whoever had the best work for the job needed, and always treated employees with respect as long as work got done. I noticed some other reviews commented on this, and I won't disregard them because every job crew was different, I can only speak on what I experienced. Overall, as a creative, I've enjoyed it and returned several times because I know the jobs will always be exciting and creatively satisfying for me, which is not something you can say for every studio. It's a great place to launch your career and make a lot of creative friends along the way with the small crews.
Cons
Obviously the con of freelancing is this may be a short term gig. Any freelancer prepares for this, and ideally, you perform well enough with a broad enough skillset that you continue to work job to job with them and make it longer term. It all depends on the ebb and flow of work. Brian likes working with those he's worked with on past successful jobs though, so the chance of return work is high even if you leave/finish out your contract. Parking can be tough during filming days, film crews like the arts district area that the studio is in.
