Unknown (Warner, Blu-ray or standard DVD, PG-13, 113 min.). You will be forgiven if you think you have seen this movie before. It is very derivative and especially recalls one of the Bourne films, as it is set in Berlin, features a car chase and has a hero who is not sure of his identity. That hero is played by Liam Neeson, adding to his growing resume of action roles, and Neeson is one of the best things about the film, directed by Spaniard Jaume Collet-Serra (“House of Wax”). With his familiar steady presence and warm voice, Neeson has become one of the most audience-friendly actors working today.

Neeson plays Dr. Martin Harris, who arrives in Berlin with his wife Elizabeth (a stiff January Jones) for a biotechnology conference. His briefcase is mistakenly left at the airport, so he goes back to retrieve it, only there is an accident en route and his cab plunges into the river. (Collet-Serra has a sure hand with action sequences; this one is good, as is the car chase that involves trolley cars later on.) The taxi driver (a fine Diane Kruger as Gina) rescues Harris, but he is in a coma for four days. Interestingly enough, his wife apparently never tried to find him. When he tracks her down, she claims no knowledge of who he is and, in fact, has another husband named Harris (Aidan Quinn in a nothing performance). As Harris tries to find out who and why there is such an elaborate plot against him, he is directed to a dying ex-Stasi (East German secret police) officer (a very good Bruno Ganz, who should have been given more to do). Frank Langella shows up 70 minutes into the film as an old friend of Harris.

The plot has many incredulous moments and one of those truly stupid expository moments in which a character explains everything instead of just killing Harris. However, Neeson and Kruger pull you in enough with their performances to make this a satisfactory ride. And while the Blu-ray version looks and sounds great, the only extras are two brief shorts — one of Neeson as action hero; the other on the characters (less than 9 minutes total) — that both give away the film’s main reveal. There also is a standard DVD and digital copy. Grade: film 3 stars; extras dog

Kiss Me Deadly (1955, Criterion, Blu-ray or standard DVD, NR, 106 min.). Writer Mickey Spillane’s Mike Hammer character has fared much better on television, where he has been played by Darren McGavin and Stacey Keach, than on film, where he even once was played by Spillane. In this 1955 film noir, directed by Robert Aldrich, he is played by a slightly uneven Ralph Meeker as a divorce detective who farms out his secretary (Maxine Cooper in her debut as Velda) to ensure the clients’ husbands are found at fault. One night, Hammer is driving when Christina (Cloris Leachman in her film debut) jumps out in front of him. As they drive off, we hear Nat King Cole on the radio and her sobbing.

Soon after, they are forced to stop by another car, interrogated and then put back into his car, which the bad guys — only seen by their shoes — force over a cliff. Christina dies, but Hammer survives and wakes up in the hospital three days later. Believing there might be a big payday, the cynical Hammer investigates. The film is noted for several things, including the reverse opening credit scroll, the scientifically impossible ending and Hammer’s easy sadism. Examples of the latter are when he fights with a man trailing him and ends up knocking him down a long flight of stairs; and when he closes a drawer on the hand of the coroner who is trying to get his cut of any loot in advance. The film is mean-spirited at times and the women are all over Hammer all the time, but the female dialogue — especially that by Gaby Rodgers as Lilly, Christina’s roommate — does not ring true. As affected as that manner of speech is, so too are some of director Robert Aldrich’s camera placements. On the whole, though, the film is visually interesting.

This edition includes the original lost ending (about a minute added), as well as the truncated ending in the extras. Director Alex Cox talks enthusiastically about the film (6:38) and there is a 1998 documentary look at Spillane (39:38), including extensive interviews with the late author, whose early career included writing for comic books, but then became a best-selling detective fiction writer as part of the first wave of original paperbacks to his the market. Another feature (9:14) looks at screenwriter A.I. Bezzerides, who has nothing nice to say about the original book (in the book, “the great what sit” was a box with narcotics in it). But then, Spillane, in his interview, has nothing nice to say about the film or Bezzerides. The film also comes with audio commentary by film noir specialists Alain Silver and James Ursini, and the booklet has an essay by critic J. Hoberman and a 1955 written defense of the film by Aldrich in the New York Herald-Tribune, as it was being attacked for its level of violence. Grade: film 3.25 stars; extras 3.5 stars

Rating guide: 5 stars = classic; 4 stars = excellent; 3 stars = good; 2 stars = fair; dog = skip it
