[[WMG: Withnail intended for Uncle Monty to rape Marwood]]
* Withnail is gay while Marwood isn't and he came on to Marwood at some point in the past and was rejected. He feeds his uncle Monty the bullshit story about ''himself'' being the one who rejected ''Marwood'' as a defense mechanism. Withnail attempts to punish Marwood for rejecting him by telling Monty that Marwood is an active homosexual in exchange for the cottage [[FridgeBrilliance knowing that Monty will probably come up there and try to rape Marwood.]]
[[WMG: One or more of the characters is a WMG/TimeLord.]]
* Specifically, Marwood is most definitely the Doctor, or possibly the eighth Doctor's son (Given their family resemblance). This, of course, makes Withnail also a Time Lord by association.
* There was a cartoon ''Franchise/DoctorWhoExpandedUniverse'' thing in which Richard E. Grant played the Doctor, with a personality not altogether unlike Withnail's. Also note Withnail's "synous nicotine based" {{technobabble}}. He must be a Time Lord too.
* They're actually all the Doctor. The film is taking place in the head of the Eighth Doctor as he lies dying and preparing to regenerate. He meets a possible next incarnation (Grant) and is also attacked by an alternate version of himself (Griffiths was rumoured to be the planned Eighth Doctor if the original BBC series had continued) trying to become real by 'having' him. Not wanting either alternative, he shaves his head, puts on a leather jacket and heads off to Manchester to become Christopher Eccleston.
* Also, the actor who plays the owner of the tearoom had previously played [[{{Recap/DoctorWhoS14E3TheDeadlyAssassin}} the Lord President of the Time Lords]]! (That's him in the page image for the story.)
** Alternatively, the film depicts [[Recap/DoctorWhoS33E13TheNameOfTheDoctor the Great Intelligence's attempt to kill the Eighth Doctor with alcohol poisoning]].

[[WMG: Marwood is an UnreliableNarrator and the reason there are so few women in the film.]]
* Marwood is quite possibly gay. Note how [[HoYay snuggly he is with Withnail]], how HaveIMentionedIAmHeterosexualToday he gets pretty much all the time, and his [[UnkemptBeauty impressive shabby chic fashion sense]]. And he's TheNarrator and the eponymous "I", so it's fair to say the film is from his perspective. Perhaps he is gay more or less to the point of being a HeManWomanHater, or at least women just don't appear on his radar. Since he's [[TransparentCloset in denial about being gay]], he's not getting laid, which combines with him being young and attracted to his roommate to make him [[YouNeedToGetLaid enormously sexually frustrated]], so he therefore doesn't notice women. The only women who have a speaking role are the schoolgirls who Withnail shouts at; Withnail, who is very important to Marwood, is capable of putting women on Marwood's radar by interacting with them.
