Ant-Man

Hank Pym: "I formally tender my resignation."
Howard Stark: "We won't accept it... formally. Hank, we need you. The Pym Particle is a miracle. Please, don't let your past determine the future."
Hank Pym: "As long as I am alive, nobody will ever get that formula."

Scott Lang: "We need a fake security guard on the inside, somebody else to hack into the power supply and a getaway guy."
Hank Pym: "No, no, no... not those three wombats!"

Luis: "We're the good guys right?"
Scott Lang: "Yeah, we're the good guys."
Luis: "Feels kinda... kinda weird, y'know."
Scott Lang: "Yeah. But we're not done yet..."

Scott Lang: "We're trapped, now what do we do?"
Hank Pym: "Do you think that's a toy tank on my key-ring?"

Luis: "Thank you for the coffee ma'am. It's not too often that you rob a place, and then get welcomed back. Because we just robbed you!"
Hope Van Dyne: "You know that he was arrested for stealing a smoothie machine, right?"
Luis: "Two smoothie machines."

Hank Pym: "You're throwing 247 off balance."
Scott Lang: "Wait, his name is 247?"
Hank Pym: "He doesn't have a name, he has a number, Scott. Do you have any idea how many ants there are?"

Frank: "Long time no see, Dr. Pym. How's retirement?"
Hank Pym: "How's your face?"

Hank Pym: "You've come for more toys for the boys?"
Howard Stark: "I came for the suit."
