I would argue it is either 1) neither necessary nor sufficient, or 2) that it is sufficient but not necessary. Which line depends on whether we are talking about something literally BEING a meme, or something merely having the potential to be a meme.

In the former case - whether something is a meme or not - having text is neither necessary nor sufficient. Adding text to an image does not a meme make, and equally some memes do not have text (or aren’t images at all).

In the latter - whether something could be a meme - adding text is sufficient to provide that potential. It may not be necessary (6-7 for example) but it could be enough.

“I have no memory of this plashe…”

That role was Alan Quartermaine in League of Extraordinary Gentleman. After that movie bombed he retired from acting altogether.

Which is a shame really because I remember it being… Kinda good? Clearly not a work of great art, but fun action silliness. Admittedly I watched it as a kid and never again so who knows really.

Jesus can you actually imagine if LOTR had Sean Connery instead of Ian McKellen? Hideous prospect. No shade to Connery, he’s played some of my favourite characters over the years, but christ that would have been a terrible mistake.
