In the first Christopher Reeve film, Superman is being interviewed by Lois Lane on her apartment balcony. Regarding his x-ray vision, she jokingly asks what color underwear she's wearing, only for him to reply that he can't tell because the planters she happens to be standing behind apparently have a high lead content. This was forgotten for a few moments, but after she walks away for a moment, he suddenly informs her that her underwear is pink. Cue her virtually teleporting back to the planters.
"Superman, thank god... I mean, GET HIM!"
Superman has just broken into Luthor's underground lair.
Lex Luthor: "Otis, take the gentleman's cape."
[Otis approaches Superman, who glares at him]
Otis: "I don't think he wants me to, Mr. Luthor."
Also Hackman's cavalier, ad-libbed "Come in, it's open" just before.
