Hennie, who starred in this year's oil rig thriller Pioneer, posted the video on Instagram along with the birthday message:
"HAPPY BIRTHDAY TO ME!!! 38 years old – I'm on FIRE!!!"
He also accompanied the gently disturbing video with a series of photographs of his beard decked out in different styles.
Hennie, arguably Norway's top male actor, is set to play the Greek hero Tydeus in the upcoming film Hercules, the Thracian Wars, alongside US wrestler turned actor Dwayne Johnson, and the British actors Joseph Fiennes and John Hurt.
He also starred in 2011's Jo Nesbø blockbuster Headhunters.
