It’s great and deceptively simple. But it feels real doesn’t it? As in, it feels like everything you’re watching is the first take - not the fourth. There is no production team or camera crew following him around 'creating' a reality. He is simply capturing and sharing his experience.
What is important to remember is this is the construct he is presenting and then delivering on authentically. Star Wars delivers authentically on a construct of a galaxy far, far away. So many adverts offer a construct, or aim for one, and deliver a wholly unauthentic experience. You only have to watch a few 'prank' style adverts to see they bottled it and didn't do it for 'real', they got the actors in and you're clearly watching the 'fourth take'.
It is also interesting to looking at this film from 2012, you can see how this style has worked its way into so much other work, whether from YouTubers or advertisers. I have certainly worked on projects which probably borrow too much from this style, without unfortunately being as authentic or effective as it could've been.
It’s hard. It is hard to say to a marketing manager at a brand “Hey! We’re going to risk the budget you’d normally and comfortably spend on tv/print/radio with the same standard/expected results, on something totally new and different that will hit the audience you actually want to get. It’s also something you will not be able to explain to your boss. We’re also just going to collaborate with XYZ, create an experience and share it with the audience. Cool?” Don’t be surprised if they politely decline. Be less surprised if they say “Ok great, but we need to ensure our logo's and messaging are present in over 50% of the film.” There’s a tightrope to walk here, but as an industry, if we can create better work, more authentic work, the results will be plain to see. I’m not saying let’s all make Casey Neistat style films, I’m saying the approach; work that is authentic to the audience, the brand and the platform can produce positive results for a brand.
Here's another film from Casey Neistat where he and a friend try out a new style McDonald's restaurant in New York.
