'The Student of Prague' is an early feature-length horror drama or, rather, it is an "autorenfilm" (i.e. an author's film). This film is a member of a movement of many movements that tried to lend respectability to cinéma, or just make a profit, by adapting literature or theatre onto the screen. Fortunately, the story of this book with moving pictures is good. Using Alfred de Musset's poem and a story by Edgar Allen Poe, it centres on the doppelgänger theme.
Unfortunately, the most cinematic this film gets is the double exposure effects to make Paul Wegener appear twice within scenes. Guido Seeber was a special effects wizard for his day, but he's not very good at positioning the camera or moving it. Film scholar Leon Hunt (printed in "Early Cinema: Space, Frame, Narrative"), however, has made an interesting analysis on this film using framing to amplify the doubles theme: characters being split by left/right, near/far and frontal/diagonal framing of characters and shots. Regardless, the film mostly consists of extended long shots from a fixed position, which is noticeably primitive. Worse is the lack of editing; there's very little scene dissection and scenes linger. None of this is unusual for 1913, but there were more advanced films in this respect around the same time, including the better parts of 'Atlantis' (August Blom, 1913), 'Twilight of a Woman's Soul' (Yevgeni Bauer, 1913) and the short films of D.W. Griffith.
An expanded universal film vocabulary by 1926 would allow for a vastly superior remake. Furthermore, the remake has a reason for the Lyduschka character, other than being an occasional troublemaker and spectator surrogate. Here, the obtrusively acted gypsy lurks around, seemingly, with a cloak of invisibility. I know their world is silent to me, but I assume, with their lips moving and such, that their world would not be silent to them, so how can Lyduschka leer over others' shoulders and not be noticed?
Nevertheless, this is one of the most interesting early films conceptually. Wegener, who seems to have been the primary mind behind this film, in addition to playing the lead, would later play the title role and co-direct 'The Golem' in 1920--helping to further inaugurate the supernatural thread in German silent cinéma.
(Note: The first version I viewed was about an hour long (surely not quite complete) and was in poor condition, with faces bleached at times and such. I'm not sure who was the distributor. I've also since seen the Alpha DVD, which, at 41 minutes, is missing footage present in the aforementioned print and also has fewer and very different title cards, but is visually not as bad. The repetitive score is best muted, though.)

Sly Stallone is hardly the finest actor in the world but compared to his brother, Frank...well, roll out those awards now! Mullet haired, muppet Frank seems to think that every part he plays, calls for him doing the role as an American/Italian Wise-guy refugee from the 'Godfather.' Please, somebody make him an acting offer 'he can refuse!' This film just stinks the place out, even by the terrible overacting in this, Frank still steals the acting dishonours. All the people compensate for their lack of talent by shouting their lines and throwing their arms about, gesticulating wildly in a style that went out of fashion back with silent films.
The plot, what there, is, makes no sense as a meteor lands and turns all the women into sex-crazed nymphets but as this is 15 certificate film, that just means they strip to their underwear and make moaning sounds like dogs on heat. What happens in the end, I'm not quite sure as I was losing the will to live long before the film finished.
Avoid this like the plague and watch 'Deep Impact' for a reasonable film about a meteor about to hit the earth.
N.B. Point of order: when one of the female leads strips down to her underwear, she has her knickers/panties under her suspenders/garter belt, it's knickers over the suspenders to allow women to go to the toilet with less fuss. A trivial point, perhaps, but shows how dumb this film is when they can't even get this right!
