A guy wants to forget his failed relationship so pays to have his memories erased, but while in those memories, he fights to not forget her.
A robot pretends to be someone’s mother.

shareAffirmative!
shareDoes a robot pretend to be someone’s mother in that one? I remember Robert Patrick on the phone with the mothers voice while the dead family was all around. But that was in #2.
shareThe terminator impersonates Sarah Connor’s mother over the phone (after having presumably killed her).
In T2 the T-1000 impersonates John’s step-mother (although he does actually mimic his mother, Sarah, later in the film so technically you’re correct. That said, is the T-1000 a ‘robot’?)
