Also: I heard these girls at the market the other day. I don't remember what they were talking about but I want to know what the other girl said.

Answer

1. How can I say to my friend "I'm watching a movie" 
(나 지금) 영화(를) 보고 있어.

2. Does the sentence change if I say "I'm watching Finding Dory?"
"도리를 찾아서"(를) 보고 있어.

3. "Do you want to watch too?"
너도 보고 싶어?

*아 진짜라니까

-라니까 comes from -라고 (말)하니까

진짜 “real, truth”
진짜 + 이다 = 진짜이다 “to be real”
진짜 + 이 + 라니까 = 진짜이라니까 ▶ 진짜라니까
진짜라니까
“I told you it's real!”

Oh, I thought you were asking about the English translation. Nvm
