hey, it says on kings knight that if you normal summon it while queens knight is on the field you can special summon a jacks knight from your deck.
1- would it work if you special summoned kings knight
2- would kings knights effect work if you had a jacks knight in your hand?

yugi moto in yugioh the movie summoned queens knight, killed familiar knight , with its effect special summoned kings knight and used thats effect to get a jacks knight

can i do this? i hope i can!

1.) No.
2.) No.

The movies and TV show are often drastically different from the real-life effects. It is NEVER a good idea to use them as references for the real-life game.
