Cultural Tip
‘Bock haben’ is a slang phrase popular with younger speakers across Germany, especially in the north. It’s perfectly fine in everyday conversation, but avoid it in formal contexts or written communication. Also, note that the preposition ‘auf’ always takes the accusative case here, so you must say ‘welchen Film’, not ‘welcher Film’.
