Type of film showing end of panic after months in space (6)

'type of film' is the definition.
'romcom' can be an answer for 'film' (I've seen this before). I'm not certain of the 'type of' bit.

'end of panic after months in space' is the wordplay.
'end of' indicates one should take the final letters.
'after' says to put letters next to each other.
'months' becomes 'm'.
'in' indicates putting letters inside.
'space' becomes 'room' (room is a kind of space).
The final letter of 'panic' is 'c'.
'c' after 'm' is 'mc'.
'mc' put inside 'room' is 'ROMCOM'.

'showing' is the link.

Can you help me to learn more?
