Arnold Schwarzenegger came back. This was a well done sequel that expands on the original. This 1991 (yes, it is old enough to order its own booze) movie had ground breaking special effects. It was also a good vehicle for Linda Hamilton as Sarah Connor. She went through extensive training, including advanced weapons handling, to prepare for the role. Robert Patrick became a SciFi icon as the T-1000 Terminator. The movie is also noted for its use of identical twins to portray both the character and the T-1000 imitating the character. One of the pairs of identical twins was Linda Hamilton and her sister, who is a nurse.
