Mark is a particularly competent actor who succeeds in granting credibility to the distinct characters he interprets, as in Biosphere... despite its apparent simplicity, he confronts one of the most difficult roles of his career. [Full review in Spanish]

| Oct 5, 2023

Though it’s stuffed full of interesting ideas Biosphere doesn’t really come together in a satisfying way, despite the engaging lead performances.

| Original Score: 2.5/5 | Sep 8, 2023

Eslyn and Duplass have made a movie that uses its limited setting and minimal number of characters well, surprising the audience with what they do with so little.

| Original Score: B | Jul 8, 2023

The best 2023 movie you just might overlook.

| Jul 7, 2023

There’s more schtick than speculation baked into the dialogue, which makes it too easy to dismiss this unfortunately stagey misfire.

| Original Score: 1.5/4 | Jul 7, 2023

Ultimately the performers are winning enough, and the ideas in the ambiguous story intriguing enough, to achieve an end result of successful middleweight charm and substance.

| Jul 7, 2023

Director and co-writer Mel Eslyn tackles big issues along the way, from gender roles, accountability, feminism and masculinity.

| Original Score: 3/4 | Jul 6, 2023

There's a sense that Duplass and Eslyn deliberately avoided any narrative or dramatic weight to the story, to keep it low-key and personal: a wise move because that's where Biosphere is the most fun to visit.

| Jul 6, 2023

I can say without hyperbole that there are conversations in this movie that I have never heard before (and refuse to spoil).

| Jul 6, 2023

Alas, there’s not enough story here to warrant a feature-length film, and the ending feels like a copout.

| Original Score: 2.5/4 | Jul 6, 2023

A fascinating curio that speaks to many contemporary issues, "Biosphere" feels like a rough draft, as it hasn't been honed to a degree that allows it to fully penetrate.

| Original Score: 2/4 | Jul 5, 2023

It’s hard to explain how the screenwriters thought they could just show two guys on a couch, calling each other “dude,” and assume audiences would be interested.

| Original Score: 1/4 | Jul 4, 2023

Biosphere, though sometimes larky in tone, is also a frowningly intense venture that never stops being about itself.

| Jul 1, 2023

Mel Eslyn’s film is a thoughtful drama about life, gender, and male friendship.

| Original Score: 3/4 | Jun 30, 2023

Like “Humpday,” it’s an act of daring — we’re waiting for the movie to cop out because most movies do. This one doesn’t, and bravo for that.

| Original Score: B+ | Sep 27, 2022

Mel Eslyn has created a funny and complicated film sure to provoke thought and discussion.

| Sep 25, 2022

An ambitious project that doesn’t develop enough to fill out the length of a feature before it basically gives up on getting out of the corner it’s written itself into.

| Sep 14, 2022

“Biosphere” is tons of fun as a character study, but its ideas will leave you gazing out of its geodesic windows, wishing there was something more out there.

| Original Score: B- | Sep 13, 2022

Post-apocalyptic survival meets the anxious buddy humor of Humpday in Biosphere, a mysterious and hilarious pic that really can’t be discussed much without saying things a prospective viewer would be better off not hearing.
