Theories of how best to "land the role" are can be great and helpful and often very "clickable". That's not to say that they are effective for everyone (anyone?). Many are based on statistics and experience, others on mere conjecture.
The following recollection is not meant to be fashioned into a formula, as a thread of events rarely repeats an exact pattern. Still, whether to satisfy simple curiosity, or to reassure irrational worries, perhaps it's constructive (if not always instructive) to share. So here is the story of "How I Got Cast In:"
Alone Yet Not Alone
This was my first full feature film experience, and my combined involvement in pre-production and production was a total of six months! In addition to my two older siblings, some of my very, very best friends now were fellow cast and crew on Alone. Shout out and hugs to all you wonderful people! :)
Back in 2010, I was apprenticing with director George Escobar of Advent Film Group. Even before the project was officially green-lit, I was assisting with the screenplay revisions, proofreading, and breakdowns, etc. Because of my familiarity with the script and source material, as well as an expressed interest in acting, I was soon officially brought on within the casting department, given the responsibility of writing the full character profiles as well as assisting with the character descriptions in the breakdown.
