Obiwan's age in Episode I, II, III and IV.

was not it 33 years between EP I & IV ? so he should be about 58 in ANH
Episode I- 25
Episode II- 35
Episode III- (speculation) 37-38
Episode IV- 57-58

That's what I thought. Luke's 19 in ANH according to the episode 4 commentary by Lucas. So Episode 3 in 19 yrs before ANH. Plus three years back to AOTC for a total of 22 years before ANH. Plus eleven between TPM and AOTC for a total of 33 years before ANH for TPM.

In TPM, Anakin's 9 and Padme was 14, Obi is 25. In AOTC Ani is 20 and Padme is 25. So Obi is 36. In ROTS, Ani is 23, Padme is 28, and Obi is 39. So plus the 19 yrs to ANH, Obi is 58. mauler is correct (and anyone else who said 58). In ANH, Ani/Vader is 42, padme WOULD be 47. But she's dead by then (for whatever reason).

Timeline with ANH = 0
1 TPM: -33 yrs before ANH
Ani 9
Pad 14
Obi 25
2 AOTC: -22yrs B4ANH
Ani 20
Pad 25

3. ROTS: -19yrs B4ANH
Ani 23
Pad 28
Obi 39
Twins born
4. ANH: 0yrs B4ANH
Ani 42
Pad --
Obi 58
Twins 19
5. ESB: +3 yrs after ANH
Ani 45
Pad --
Obi --
Twins 22
6. ROTJ: +4yrs After ANH
Ani 46
Pad --
Obi --
Twins 23

Padme should be about 28 when she dies... 🙁

looks like that is about right to me... nice list mep

It seems rather odd to me that ROTJ is a year past ESB, but that's what all the "official" timelines say. I know they aren't as close together in time as the time between the last two matrix movies (which was like ten seconds), but it seemed at the end of ESB that they knew where Han was going: to Jabba's. Maybe ESB is in SW Universe version of November and ROTJ is in like February (but in their time measurements and increments, but you get what I mean...). That's always sorta made me wonder...

a lot of people seem to think Obi Wan looks well into his '70's but Sir Alec Guinness was 63 years old when he did Star wars.

37-38 yes,56-58 no,you have to add 20 years to his age from ep3,becouse luke is around 20 in ANH,in the star wars game for super nintendo lukes bio says he's 19

Yup, it is only a small difference between the ages of Guiness and Obi-Wan; no biggie.

I reckon:
Ep1
Obi 25 Anakin 8
Ep2
Obi 35 Anakin 18
Ep3
Obi 40 Anakin 23
Ep4
Obi 58 Anakin 41

(Luke & Leia were meant to be 18 in "A New Hope"😉

Hopfully that's helped you all out

Actually, in the ANH commentary, George says they were supposed to be 19. He mentions this when he discusses the actors ages vs. the characters. He says Mark was 24 when they filmed and Carrie was 19, the age he wanted them to be. I'm sticking with his numbers thank you very much. So there's nineteen years between III and IV. That's why the math works out to TPM being 33 years before ANH. One way we could settle this is to find out what the opening crawl to ROTS says. I've been going by the "official" timelines on starwars.com which they also put in all the books so you know when the books take place in regard to the films so you know how old the characters were supposed to be. Different sites are reporting ROTS is 2 years after AOTC and some say 3. starwars.com says 3. Which makes them nineteen when you work the math from Episode 1, or back from Episode IV as I did a couple posts up.
