[4] Variety: Mentions "Fyffe-Marshall, Tamar Bird, Sasha Leigh Henry" and "Best Animated Short Hot Flash" etc. This source does not appear to be about the actor Henry Marshall, but rather about Canadian Screen Awards. I must be careful not to conflate "Henry Marshall" with "Sasha Leigh Henry" or "Fyffe-Marshall".

Checking word count:
Draft 1 is very short (approx 80 words). I need to reach 180-260 words.
Wait, the prompt says "Write a 180-260 word career overview". If the sources don't provide enough info, I cannot invent it.
Re-evaluating sources for more info:
[1] TMDB: 4 known credits.

Problem: The provided sources are extremely sparse. There is almost no biographical information (no birthdate, no place of birth, no gender, no specific roles).
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess... If a detail is not in the provided material, you omit it rather than guess."
Conflict: The user wants 180-260 words, but the sources only provide about 40-50 words worth of unique facts.
Strategy: I must expand on the facts provided without inventing anything. I can list the titles and years provided. I can mention the different databases that list his work. However, if I strictly follow "If a detail is not in the provided material, you omit it rather than guess," I cannot reach 180 words without repeating myself or being extremely verbose about the sources themselves.
Let's look closer at the sources:
