Early Career and Breakout

Heizer’s first appearance on screen came in 2005 when he played Joshua Lipnicki on the medical drama ER for four episodes, as recorded by Fandom (the fan wiki). Two years later, he landed his first film role — Davey Danner in the drama Rails & Ties (2007), directed by Alison Eastwood, per Wikipedia (the online encyclopedia).

Heizer played Joshua Lipnicki on ER for four episodes.

His first film role was Davey Danner in Rails & Ties (2007).

  • After Rails & Ties, Heizer appeared in Rudderless (2013) as Josh, a role that brought him into the indie film circuit.
  • He then took on Memoria (2015) as Simon, and The Stanford Prison Experiment (2015) as Marshall Lovett, both cited by Wikipedia.
  • His most prominent pre-Netflix role was Drew Holt on Parenthood, a recurring character from 2010 to 2015, according to Fandom.

The pattern: Heizer built a resume of guest spots and supporting roles before landing the Netflix role that would define his career. The trade-off: despite the visibility of 13 Reasons Why, he hasn’t yet transitioned into lead film roles.

Filmography Highlights

Heizer’s filmography spans a dozen titles, with a notable concentration from 2015 to 2018. Here are the key credits, all sourced from Wikipedia unless noted.

  • Nerve (2016) – Tommy Mancuso. A thriller about an online dare game, co-starring Emma Roberts and Dave Franco.
  • Roman J. Israel, Esq. (2017) – Kyle Owens (Teenager #1). A small role in the legal drama starring Denzel Washington.
  • Love, Simon (2018) – Cal Price. A supporting role in the groundbreaking teen rom-com.
  • Ex-Husbands (2023) – Mickey Pearce. A recent indie film, though confidence in the release date is medium per Wikipedia.
  • People We Meet on Vacation (2026) – David (reportedly). Listed on Rotten Tomatoes (the review aggregator) with medium confidence.
The upshot

Heizer’s filmography is light on lead roles but rich in ensemble work. For fans of 13 Reasons Why seeking his other performances, Love, Simon and Nerve offer the closest parallels in tone and audience.

The implication: Heizer’s filmography remains ensemble-heavy, limiting his leading-man opportunities.

The 13 Reasons Why Era

Heizer’s portrayal of Alex Standall in Netflix’s 13 Reasons Why ran from 2017 to 2020 across all four seasons. The character is a central figure in the story of Hannah Baker’s suicide, and Heizer’s performance was widely noted. According to IMDb (the film database), he appeared in 48 episodes. The German Wikipedia pegs the count at 49 episodes, while the Norwegian Wikipedia says 46

The show’s impact on Heizer’s visibility is undeniable. Before 13 Reasons Why, his most recognized role was on Parenthood; after, he became a household name among young adult audiences. Yet the role also typecast him — his subsequent projects, like Ex-Husbands, have struggled to find wide distribution.

Consequence: Heizer’s peak from 13 Reasons Why may typecast him unless he secures a lead role in a different genre. For casting directors, he offers proven dramatic range in teen-focused content. For indie filmmakers, he remains a reliable supporting actor with a built-in fan base.

What this means: Heizer’s peak exposure may have typecast him for teen roles, limiting his range in the eyes of mainstream producers.

What’s Next for Miles Heizer

The only confirmed upcoming project is People We Meet on Vacation, a film adaptation of Emily Henry’s novel, with Heizer reportedly cast as David. However, the project is listed on Rotten Tomatoes (the review aggregator) with medium confidence, and no official production start date has been announced. Beyond that, Heizer has no publicly listed TV or film commitments as of early 2025, according to Wikipedia.

What to watch

If Heizer’s next major role is in a streaming series, it could signal a repeat of the 13 Reasons Why pattern. If he pivots to independent film leads, it would mark a deliberate shift away from teen dramas. The lack of announced projects may indicate a hiatus or unannounced development.

The pattern: Heizer’s career crossroads may determine whether he remains a teen-drama fixture or broadens into indie leads.
