WATCH: Aussie action star Chris Hemsworth's snowy Prague train ride

Movie star Chris Hemsworth is in Prague to film 'Extraction 2' in a four-month shoot expected to last until March.

Last week director Sam Hargrave shared a snowy teaser from the Czech Republic on his Instagram account, confirming that filming has begun on the sequel to Netflix’s action hit starring Hemsworth as black-ops mercenary Tyler Rake.

Now the film's Australian lead can be seen in a short video posted to his Instagram account on Friday, declaring a pretty chill start to the shoot.

The video also features Hargrave and a somewhat bloody-looking Hemsworth hurling through the wintry Czech landscape on a vintage-looking train.

“First day shooting on Extraction 2,” Hemsworth says in the video, "We're here in Prague...two things are different from the last film. One: very very cold. Two: I’m alive. How? You’ll have to find out. Watch the movie. Stay tuned.”

According to the Hollywood Reporter, the first 'Extraction' was viewed on Netflix by an estimated 90 million households upon its release in April. The sequel was written by 'Avengers: Endgame' filmmaker Joe Russo, who also wrote the first film.

Prior to shooting, Hemsworth posted some shots of Prague downtime enjoying a cream-filled trdelník in the city center with wife Elsa Pataky, writing:

“Here in Prague, thankful to have my wife teaching me her fine European dining skills.”

'Extraction 2' is just one in a long line of productions being shot recently in the Czech Republic. Despite the Covid pandemic, more Hollywood film productions are being made in the Czech Republic than ever before.

Next year will see even more Hollywood investment, and according to the volume of orders for Hollywood filmmakers to shoot in Prague, the current period is the strongest ever.

The Czech Film Commission is calling for increased incentives to capitalize on this unprecedented interest. Some sources claim a high-budget film adaptation of the horror story 'Nosferatu', starring Anya Taylor-Joy, star of 'The Queen’s Gambit,' could be the next major movie to be shot in Prague.
