@version none of those really strike me as particularly homoerotic
I guess you could read
Thelma + Louise as queer coding on a deep level but seems v 2020 retrospect
the standard reading of a feminist take/inversion of yr typical buddy road movie seems much more the point
Sam + Frodo - I mean there's tenderness, but no sexual tension. (and there's no way Sam isn't 100% straight)
the M.A.S.H. are coded straight in the way virtually all 70s leading men are. there's maybe an unusual depth of friendship, not erotic tho.
