I believe the answer is:

flicker

I'm a little stuck... Click here to teach me more about this clue!

'easier dance' is the definition.
'flicker' can be an answer for 'dance' (thesaurus). I am not sure about the 'easier' bit.

'film extremely' is the wordplay.
'film' becomes 'flick' ('flick' can be a synonym of 'movie').
'extremely' becomes 'er' (I am not sure about this - if you are sure you should believe this answer much more).
'flick'+'er'='FLICKER'

Can you help me to learn more?

(Other definitions for flicker that I've seen before include "Glimmer" , "Woodpecker" , "Shine unsteadily; waver" , "Twinkle" , "Vary rapidly in brightness" .)

I've seen this clue in The Telegraph.
