who is barry and ziggy in big little lies

Barry and Ziggy in Big Little Lies are a bit mixed up in fan talk, but Ziggy Chapman is Jane’s son, played by Iain Armitage. There doesn’t appear to be a major character named Barry in the main cast or character list for the series, so “Barry” is likely a mistaken name, a minor/uncredited character, or confusion with another show or actor.

Ziggy

• Ziggy is Jane Chapman’s young son.

• He’s one of the central children in the story and becomes important when school and family tensions build up.

• The character is portrayed by Iain Armitage.

Barry

• I couldn’t verify a notable Barry character in the core Big Little Lies cast or character guides.

• If you saw “Barry” in a forum post, it may have been shorthand, a typo, or confusion with a different character or actor mention.

Quick take

• Ziggy = Jane’s son.
• Barry = not a known main character in the series.

TL;DR: Ziggy is Jane Chapman’s son in Big Little Lies ; Barry doesn’t appear to be a recognized main character in the show’s cast lists.
