Michael Peña has nothing but well wishes for Jeremy Renner after his snowplow accident ... saying he hopes he makes a full recovery, after saving lives on and off camera.

We caught up with Michael at LAX and asked all about his fellow Marvel Cinematic Universe star ... who's, of course, healing after a snowcat crushed him -- shattering more than 30 bones -- while he was trying to rescue his nephew.

Michael tells us, he hopes Jeremy fully recovers soon. In his words ... 30 is whole a lot of bones to break, so he's wishing him the best of luck.

You could tell he was pleasantly surprised at how positive Jeremy's been through such a horrific situation.

In case you didn't know, both actors are part of the MCU -- Michael in the 'Ant-Man' franchise and Jeremy in the 'Avengers' flicks -- plus, they costarred in "American Hustle."

While this obviously sucks for JR ... who won't be able to work for a while ... MP says Disney should hold the Hawkeye role until he's ready to get back in action.

New video shows Jeremy Renner's helicopter flight to a hospital shortly after his horrific snowplowing accident, and TMZ has learned new details about his injuries which caused him to lose a serious amount of blood.

The video, obtained by TMZ, starts right after the two-time Oscar nominee was loaded onto the chopper Sunday around 9:50 AM. Eyewitnesses tell us Jeremy was plowing the road about a quarter mile from his Tahoe home so his family could get out after a massive New Year's eve storm.

According to a neighbor, the plowing machine -- called a Snowcat -- accidentally ran over one of Jeremy's legs, and he was losing a lot of blood from the injury. We're told another neighbor, who's a doctor, was able to put a tourniquet on his leg until paramedics arrived.

We're told the area was treated like an active crime scene ... with police arriving at 8 PM to impound the Snowcat, which Jeremy's previously posted video of himself using on his property after snowstorms. The issue, we're told, is the machine has extensive safety features, and should not have rolled over Jeremy.

As we reported, Jeremy is in "critical but stable condition with injuries suffered after experiencing a weather-related accident while plowing snow" ... according to a rep.

According to dispatch audio, obtained by TMZ, first responders were initially concerned about the conditions to access the accident due to the storm.

A source close to Jeremy tells us his injuries are "extensive" -- along with his leg, other parts of his body have been injured.

Jeremy Renner was seriously injured during a snowplowing accident at a Nevada ski resort -- and had to be airlifted to a hospital.

The two-time Oscar-nominated actor was in "critical but stable condition with injuries suffered after experiencing a weather-related accident while plowing snow earlier [Sunday],” a rep told Deadline.

The rep says Jeremy's receiving excellent care, but would not disclose details about the accident or the injuries.

Renner has a house in the Mount Rose Ski Tahoe resort near Reno, which got slammed by a snowstorm on New Year's Eve. Thousands of homes in the area apparently lost power ... it's not clear if Jeremy's house was also impacted.

As you probably know, Renner was nominated for an Academy Award in 2010 for his performance in the film, "The Hurt Locker." The following year ... he got another Oscar nom for his role in "The Town." He has also starred in countless other movies, including "The Avengers" and "Captain America: Civil War."
