Scientist invisible

Making a magnificent screen debut, Claude Rains stars as a scientist driven mad by an invisibility potion in this adaptation of H.G. Wells's classic story. Featuring groundbreaking special effects, the film follows the increasingly demented Jack Griffin (Rains) on his murderous rampage through an English village as he searches for the invisibility's cure. The police, Griffin's girlfriend (Gloria Stuart), and his fellow scientists race to capture the Invisible Man before before he kills again and before he realises his goal of world domination.    

  Hollow Man 2  is a 2006 American  science fiction   horror  film directed by  Claudio Fäh  and starring  Peter Facinelli,  Laura Regan  and  Christian Slater. It is the stand-alone sequel to the film  Hollow Man. It was released  direct-to-video  on May 23, 2006   The movie opens at a cocktail party at the Reisner Institute, a Washington  think tank, some time after the events of the first movie. An invisible force drags a scientist named Dylan into a nearby bathroom, where the force (implied to be a person) brutally throws Dylan around for information. Dylan mentions another scientist, Maggie Dalton, who knows the "formula" the invisible person is looking for. Apparently accepting this, the invisible person releases him, warning him not to tell anyone he was there. As soon as the invisible man leaves (or rather, pretends to leave), Dylan attempts to call someone on his cell phone, but the invisible man smashes the phone and slashes Dylan's throat. The police arrive at the laboratory to conduct a murder investigation, but the laboratory's military supervisor, Colonel Gavin Bishop, insists it is an internal military situation and the police have no jurisdiction. Fearing attacks on the remaining scientists, the lab's owner, Dr. William Reisner, employs Frank Turner and his partner, Detective Lisa Martinez, to protect Maggie, but refuses to divulge any information on the nature of his work.
