    Good thing the nearest candidate is 700+ ly away....

    I blame George Lucas for turning the parsec into a unit of time.

    There is actually an explanation of this in one of the later movies
    (/Solo/?).

    Basically, he exited a maze by cutting through the walls, thus
    reducing the distance required.

    But I agree that his boast makes /no sense at all/ without the

    I don't recall noticing it anywhere else. But, of course, I don't go
    around thinking about units all day either.

    And a "light year" is a measure both of space and of time. If SETI
    discovered a signal from 10M LY away today, the civilization that sent
    it existed 10M years ago, but may not be around now. So we would still
    not know that we are not alone in the universe, just that we are not
    the first. Which is not the same thing.

    This all gets very confusing, and what I said just now may well be ...
    bunk. Who can say?

    There is actually an explanation of this in one of the later movies

    I have a vague recollection that somebody mentions in an expanded universe book that it involves a path by a black hole and you can cut the distance by going closer to the black hole at the serious risk of not completing the run

    I think in the movie there's a reaction from Obi-wan that suggests that he recognises that Han is bullshitting but isn't in a position to call him on it because they need to get on a ship and the falcon seems to be the only option for that (I think
    the actual shooting script specifies a reaction)

    Yeah, here it is (from https://app.studiobinder.com/company/580e85847e7982164664e844/collab/5e3cc9ed9287d4071d44d0a0/projects/5e3cc17d9287d4071d44cfa6/document/5e3cc18d670d63a57455f38a?filter=%257B%2522l%2522%253A%25225e3cc1a4b039d999679bfb90%2522%

    HAN
    It's the ship that made the Kessel run in less than twelve parsecs!
    Ben reacts to Solo's stupid attempt to impress them with obvious misinformation.
    Yup:
    "Ben reacts to Solo's stupid attempt to impress them with obvious misinformation."
    That version of the script also confirms that Han shot first, and includes the encounter
    between Jabba and Han that didn't appear until the cgi-enhanced release 20? Years later.

    The Jabba and Han meet was scripted, filmed but cut from the movie

    And then, apparently, it's dialog was re-purposed, as it appears in
    the original release in a different context.

    Similar to an added lost scene in /Spartacus/, where the dialog is the
    same as another scene which wasn't lost.

    You do not have a coherent movie when the dialog is re-used (unless
    there is a reason to re-use it, such as a court reporter reading it
    back).

    If you mean the bit in _Star Trek II_, ><https://en.wikipedia.org/wiki/Komagata_Maru_incident>
    was not that. Very short version: The British Empire
    was racist. Of course.

    He probably is referring to Cap'n Kirk's ... imaginative ... solution
    to a Space Academy exercise, but equating cheating on a test with what
    Han (in a much later film) is credited with doing is ... valid only in
    that is shows what true determination can do. If at that.

    Kirk is motivated by pride -- pride wounded by his "failure". Solo,
    IIRC, basically has a gun to his head and no option but to take risks.

    It's theatrical. I don't know if this is
    relevant, but I recently heard a BBC radio
    feature about film making, with particular
    reference to dreams, and I think a few people,
    including one of the hosts, made an argument
    that all films are simulated dreams.
    Criticism of this includes, do you know
    people who throw popcorn around while
    they're dreaming? Anyway, _Screenshot_: ><>https://www.bbc.co.uk/programmes/m001vlnx>
    - I think that will allow an audio download.

    In shows with music, a song from earlier
    often reappears later.

    And often with a different meaning. Even using the same words.

    A clear example of this that might be accessible is "Thank You Very
    Much" from the Albert Finney /Scrooge/.

    Which is part of another musical tradition: to recap the songs at the
    end for the Finale.

    In stage versions, sometimes the whole cast turns up singing,
    including those who have died in the story. An example would be /Into
    the Woods/ or /Sweeny Todd/, but you need to be watching the version
    shown on TV (which is available on DVD), not the theatrical film done
    later -- this doesn't often survive the transition to a theatrical
    film.

    Note: by "TV version" and "theatrical film" I am attempting to
    distinguish between an actual stage play which has been filmed (often
    to be shown television or a filmed live TV performance) and a film of
    the musical done as a movie intended to be shown in movie theaters.
    Time travel isn't the /only/ area in which normal speech fails us!

    Incidentally, the Marvel Comics Star Wars
    adaptation also had the scene where Jabba
    the Hutt, as a humanoid-ish figure, confronts
    Han Solo.
