Screenwriting

Speculative Biology

Invent alien life that evolves by real biological rules.

Which is right for you?

Choose Screenwriting if…

  • Hearing characters talk back to you on the page is a real rush.
  • Rewriting and cutting scenes you loved feels like craft, not failure.
  • You can keep going knowing almost nothing you write gets filmed.

Choose Speculative Biology if…

  • You like redesigning a creature once you realize its metabolism can't work.
  • The moment a creature clicks into a coherent ecosystem is enough payoff.
  • Rabbit holes into convergent evolution and metabolic scaling sound fun.

Before you commit

Screenwriting

  • A second act that sags every single time would defeat you.
  • Format rules and parentheticals turning ideas into homework would kill it.
  • Brutal feedback on pages you slaved over would be too much.

Speculative Biology

  • Nobody seeing the years of logic behind one drawing would deflate you.
  • You want a tangible result, not notebooks and tab-stacks of evolutionary logic.
  • Starting a design over because the biology doesn't hold would frustrate you.
