This was Keaton's first feature and is in actuality three shorts, set in different periods (Stone Age, Roman Age, Modern Age) on the eternal triangle of romance. The stories parallel each other as in Griffith's INTOLERANCE, which this was intended to satirize. The strengths of the jokes and gags almost all rely on anachronisms, bringing modern day business into ancient settings.

Here are the classic moments:
Using a turtle as a wee-gee board (Stone Age); A wrist watch containing a sun dial (Roman Age); A chariot with a spare wheel (Roman Age); Using a helmet as a tire lock (Roman Age); Early golf with clubs and rocks(Stone Age); Dictating a will being carved into a rock (Stone Age); The changing weather forecaster (Roman Age); The chariot race in snow -Buster using skis and huskies with a spare dog in the chariot's boot(Roman Age).
The above are all throw-away gags that keep us chuckling. There are however unforgettable moments as well:
Buster taking out shaving equipment to match girl putting on make-up; The fantastic double take when an inebriated Buster gazes at his plate to discover a crab staring up at him (within one second he has leaped to stand on his chair from a sitting position and leaped again into the arms of the waiter - one of the funniest moments I've ever seen). And that lion - the manicure -just brilliant.
There's also an off-color bit of racism when four African-American litter bearers abandon their mistress for a Roman crap game.
Kino's print is a bit fuzzy and contains numerous sequences of both nitrate deterioration and film damage- most probably at ends of reels. The Metro feature is scored with piano and flute and borrows heavily from Grieg.
Lots of fun and full of laughs.

With a title "borrowed" from Werner Herzog and liberal helpings of Kubrick, Haneke and Noe it is painfully obvious that Thomas Clay considers himself a cut above the usual sort of rubbish our British cinema churns out. "Robert Carmichael" (for short) sets itself up as a realistic study of youthful alienation and at the same time seemingly a critique of the Iraq war. The problem with the realism is that the characters are so patently unrealistic and atypical - contrary to the fetid imaginings of "extreme" filmmakers most teenagers are not drug addled rapists. As a critique of the Iraq war, a film about youth violence (by a talented classical musician - subtext society has damaged this sensitive individual)is so infantile as to hardly bear thinking about. There are signs of technical ability but some reviewers have overstated this. Like Kubrick and Noe he does show that the desire to shock linked with supposed serious intent may be the worst cinematic con trick of recent film. People liked "Clockwork Orange" and "Irreversible" because they liked the rapes and the violence, but most of all they liked feeling culturally superior for liking things that most hated. So too much Kubrick and not enough Haneke (a serious and moral filmmaker) here labels this as one of the most moronic films in years. (I am not against violence in film. To do it seriously is a hard trick though - people in cinemas cheered Alex in "Clockwork Orange" showing how Kubrick's supposed intent was missed by miles. Gratuitous violence is much easier to achieve and is less offensive than the pretensions of many art-film directors.)
