From time to time, Wizards/Hasbro decides to create Special Guest Gift Cards given to Events as a present to some personalities to honore them as MTG fans.
The Actors Special Guest Gift Cards were made on a different card stock by a third party. They have the size of normal MTG cards and a glossy back. They were sent to their managers before the Hollywood Pro Tour that took place on May 23-25 2008, trying to get those actors to come to the Pro Tour. At least 15 to 20 sets (45-60 cards) are supposed to exist. Each actor was sent a set and remaining cards were distributed to WotC employees involved in the project.

The Robot Chicken is not a real card but a color copy sticker glued to a MTG card. Apparently, they were given after PT San Diego to the Robot Chicken writers attending it. According to only one Robot Chicken Writer, there's at least 6 given in existence. No further info is available at the moment.
The card number 42/1138 refers to:
42: The Hitchhiker's Guide to the Galaxy as the "Answer to The Ultimate Question of Life, the Universe, and Everything". 1138: One of George Lucas' early short films was Electronic Labyrinth: THX 1138 4EB, later remade into the feature film THX 1138. After the film, references to 1138 (and sometimes to THX) are scattered throughout Lucas' films, Lucasfilm productions and LucasArts computer games.
*Robot Chicken is a show that combines chaos, action figures, and hilarity to keep gamer-centric personalities rolling on the floor with laughter. But it turns out that behind all the pop-culture references, the action figures, and the chaos of their writers’ meetings, the staff at Robot Chicken are big Magic fans.
