Larry David is back on HBO Max with "Life, Larry and the Pursuit of Unhappiness," an American history-themed sketch comedy that arrives after the end of his long-running HBO run with "Curb Your Enthusiasm." One of the biggest talking points around the new series has quickly become its stream of guest stars and surprise appearances.

According to The Hollywood Reporter, the show's cameo roster is already notable through episode four. The lineup includes an opening appearance from Barack Obama, while Rob Reiner's involvement is being highlighted as a poignant final screen role. That combination alone shows how broadly the series is reaching for recognizable faces.

The report centers on which performers have shown up so far and the roles they take on within the show's history-driven sketches. Rather than relying only on Larry David's signature style, the series appears to be building momentum through a deep bench of familiar names, adding another layer of appeal for viewers following each new episode.

With only a handful of episodes out, "Life, Larry and the Pursuit of Unhappiness" is already shaping up as a cameo-heavy comedy event. The early guest list suggests the HBO Max series is aiming to blend satire, historical riffs and star power into one package as it continues its first run.
