Leo's (Anthony Mackie) arms when he runs resemble the way the Terminator T1000 runs after Sarah Conner and T800 in O Exterminador do Futuro 2: O Julgamento Final (1991).
A comment made by Leo about wearing "sunblock 500" in case of nuclear attack mirrors Sarah Connor's comment of "wearing sunblock 2 million" of another nuclear attack in O Exterminador do Futuro 2: O Julgamento Final (1991), another robot/android movie.
There are several ties between Anthony Mackie's character and his appearance in the Marvel Cinematic Universe (MCU). He is often referred to as "Cap", is called a "war machine", and even states that "I could do this all day."
