Eastern princesses I see rushed into short film (9)

'eastern princesses' is the definition.
'maharanis' can be an answer for 'princesses' (maharani is a kind of princess). I am unsure of the 'eastern' bit.

'i see rushed into short film' is the wordplay.
'i see' becomes 'aha' (both are said after realising something).
'rushed' becomes 'ran'.
'into' means one lot of letters goes inside another.
'short film' becomes 'mis' (I can't justify this - if you can you should believe this answer much more).
'aha'+'ran'='aharan'
'aharan' placed into 'mis' is 'MAHARANIS'.

Can you help me to learn more?
