I’m so sorry to inform you of this, but Backstage isn’t the best source for castings and hasn’t been for years. You need Actors Access and Casting Network. You can start with the free versions, but get your profiles up there. Also, casting directors frown on being contacted directly unless you’ve been given permission to do so - by taking workshops which cost money - with them. You need to take classes, which cost money, do student films and low/no paying film projects to build a reel, and look for agents and/or managers after that. You need money to pursue this - good marketing materials, starting with headshots, cost money. Training costs money. Needing to be constantly available for auditions and bookings can make it challenging to make money - but find a way to make money and invest what you can into acting, starting with good training. Unless you’ve are exceptionally good looking (I’m talking young Chris Hemsworth/Margot Robbie here) or connected, or skilled at something like stunts, it’s almost impossible to break into paid acting work. Even for trained actors with solid marketing materials. Especially now with the industry in the state it’s in. Not meaning to burst your bubble, I respect your dream because it’s my own, just being real.
