The supplied article text contains only the headline and website navigation, so it does not provide enough information to establish what happened, why Rose Byrne was affected, or why the story matters. The headline says a 2013 British comedy “scarred” Byrne and left her “hijacked by this fear”, but gives no supporting explanation.

No plot details, quotations, production context, dates beyond 2013, or other factual information are included in the provided extract. A fuller article text would be needed for a clear and reliable summary.
