In Korean, you connect nouns with 와 after a vowel-ending noun and 과 after a consonant-ending noun. Since 책 ends in the consonant ㄱ, you attach 과 to get 책과.

Why is 가 attached only to 영화 and not to 책?

When you list multiple nouns with 와/과, only the final noun takes the subject particle (이/가) to mark the whole phrase as the sentence’s subject. Here 영화 is last, so we say 책과 영화가.

Could I use 이랑 or 랑 instead of 과?

Yes. 이랑 (after consonants) and 랑 (after vowels) are colloquial equivalents of 와/과 meaning ‘and’. Since 책 ends in a consonant, you’d say 책이랑 영화가 재미있어요. Note that you cannot drop the initial 이 after a consonant (so 책랑 is incorrect).

Can I use 은/는 instead of 가 here?

You can say 책과 영화는 재미있어요, but the nuance shifts. 는 is a topic marker and often implies contrast or sets a general topic (“As for books and movies…”), whereas 가 neutrally marks the subject you’re describing.
