Murch asked for Reel 2, Dialog Track 2, in the abbreviated form "R-2-D-2". Lucas, who was in the room and had dozed off while working on the script for Star Wars, momentarily woke when he heard the request and, after asking for clarification, stated that it was a "great name" before going back to writing his script.
They aren't abbreviations — they're model and serial numbers. R2 is a second generation R-series astromech, serial number D2. * And C-3PO is a C-series protocol droid with the serial number 3PO. *And likely several more numbers that get dropped for the sake of time.
R2-D2 was present when Padmé gave birth to Leia and Luke, so he knew Luke was Anakin's son – but what he didn't know was that Anakin became Darth Vader. In addition to that, Anakin's fall was surely a painful event in R2-D2's life, one that he definitely wouldn't like to remember or even talk about.
Binary, also known as droidspeak or astromech, was the language commonly spoken by droids. It consisted of a set of beeps and whistles strung together into what resembled sentences. The C1-series astromech droid utilized this form of communication, as did Industrial Automaton's R2 series astromech droid.
C-3PO, his robot companion, could speak 6-million languages including excellent English with a hint of a British accent and all R2-D2 could muster were beeps and whistles. Clearly the technology was there to let him speak, but whoever designed him intentionally decided to stick with the beeps and whistles.
To make R2-D2's “voice,” Burtt recorded sounds with his own voice and played them back at higher speeds. Then, he combined those recordings with sounds he made on a synthesizer. It's hard to say whether Ben Burtt heard or recorded the songs of a bobolink when designing sounds for R2-D2.
Darth Vader acts like he doesn't even know C-3PO or R2D2. They were with him since he was a child. He did everything he could to forget his past. Also, his plating had been replaced many times, and protocol droids all look very similar.
Towards the very start of George Lucas' creation of R2-D2, both he and C-3PO had speaking roles, leaving R2-D2's trademark bleeps without a place in the story. This plan was abandoned eventually, but C-3PO does often explain to the audience that R2-D2's bleeps often translate to swear words.
However, the same could not be said for R2-D2, who never had his memories erased. While there isn't a canonical reason for this decision, the likely explanation may have been that Threepio was more likely to say something he shouldn't have.
The Invasion of Naboo. R2-D2 repairs the shield generator of Queen Amidala's Royal Starship. In 32 BBY, R2-D2 was in the possession of the Royal Engineers of Naboo, and was assigned aboard Queen Amidala's Royal Starship as a maintenance droid.
C-3PO is a droid. "He" is only even a "he" because someone opted to give him and leave him with a male voice. He's a protocol droid, not a sex toy, so he does not appear to have any sort of sexual functions at all.
secondly, in Legends, R2 was given programming that actually restricted him. from sharing any information with Luke or Leia. about their parents or relation to one another. this was all part of the plan. to conceal this information from the twins.
R2 was later able to restore his companion during the Battle of Geonosis. After the battle, R2-D2 and C-3PO were the sole witnesses to the marriage of Anakin Skywalker and Padmé Amidala in Lake Country. After this Padmé gave ownership of R2 to Anakin while she kept 3PO.
Since Obi-Wan and Anakin often fought together, Obi-Wan was friends with R2-D2 as well. This means that although R2-D2 might not have immediately recognized Obi-Wan on Tatooine due to his age, Obi-Wan should have recognized the droid.
But only a few of the human characters in Star Wars can understand droids; Luke Skywalker wasn't the only one. Obi-Wan Kenobi was another human who could speak Binary, as well as Anakin, who shared the strongest relationship with R2-D2, as seen in the prequel trilogy and Star Wars: The Clone Wars.
Because he never owned a droid. R2-D2 was owned by Padme and later Anakin, and after that Bail Organa. R4-P17 was assigned to him to assist, not given to him to own. So he really never owned one.
in the Dark Horse comic series star Wars Tales, which is now part of legends, it's revealed that Darth Vader did recognize C. 3PO on Cloud City. when 3PO was shot by Stormtroopers, his parts were brought before Vader. because the Imperials thought he could hold valuable.
Burtt is notable for popularizing the Wilhelm scream in-joke and creating many of the iconic sound effects heard in the Star Wars film franchise, including the 'voice' of R2-D2, the lightsaber hum, the sound of the blaster guns, the heavy-breathing sound of Darth Vader and creating the Ewoks' language, Ewokese.
