My thanks and full credit to IMDB, because this moderator has only seen bits and pieces of this movie.
+ Helen Slater, as previously mentioned, played the titular role in the 1984 Supergirl movie. Kara Zor-El, her Kryptonian name, is the older cousin of Kal-El (aka Superman).
+ In Man of Steel, Russell Crowe played Jor-El (aka Superman), the biological father of Kal-El (aka Superman).
+ The skinhead/neo-Nazi dude’s tattooing is supposedly identical to that worn by the Aussie skinhead/neo-Nazi character Hando, whom Russell played to critical acclaim in the Australian movie Romper Stomper.
In the continuing age-old debate of who was the best captain on Star Trek, Grant and Supergirl pass the time by arguing the merits of James T. Kirk (William Shatner) and Jean-Luc Picard (Patrick Stewart).
Mary: You know I once served a medium rare swiss steak to Patrick Stewart.
Zack Grant: Who’s Patrick Stewart?
Mary: Patrick Stewart, Picard, The greatest starship captain that ever lived.
Zack Grant: What about Kirk? Captain James T. Kirk?
Mary: Old news.
Zack Grant: What? What? You’re shunning the guy who went first where no man had ever been before?
Mary: He was a D-Type. Sub-A.
Zack Grant: Hey, he kicked Klingon ass, baby.
Mary: He was always breaking the prime directive, Picard never breaks the prime directive.
Zack Grant: That’s because he’s an old bald guy from Liverpool, he couldn’t break a date.
Mary: Oh! For Pete’s sake, grow up!
Zack Grant: Grow up, I don’t believe you sometimes…
Mary: How about you, Yuji? Who do you think was best?
Zack Grant: Oh yeah right, ask him…
Mary, Zack Grant: Sulu?
Yuji: He should have been Captain.
