This was a pretty good action movie with believable characters, given the genre. The ex- soldier Lasko sick of death and hiding out in a monastery (Mathis Landwehr) reluctantly takes up the gauntlet to be the Vatican's point man in a struggle against terrorists centered on a train bearing pilgrims from Cologne Germany to Lourdes.
You also have a deadly virus, helicopters, explosions, martial arts fights in and on top of the moving train, rockets, guns, knives, the works. Pretty good pyrotechnics too. The single most unbelievable thing in the plot is when a henchman parks his truck right across the tracks while waiting to pick up the bad guys, anticipating the train will stop before it hits him, thinking the bad guys control the engine. I cannot believe anyone would not simply have parked a few meters away, just off the tracks. Too stupid to believe even of idiots.
I could more readily swallow Vatican secret agents than that incident, though who knows. There were military orders of monks during the crusades.
Mathis Landwehr looks to be in great shape in the early scenes when he is shirtless. He has a fine physique: lean but muscular and looks completely believable as a martial artist.
I hope they do a sequel, as the title suggests. In English it was Lasko:Death Train. That suggests Lasko: the Next Adventure. I would watch it.
