How to get better at speaking Hindi? - 15M living in UK

Im 15 and live in the uk. i grew up watching indian films when i was younger and thats where i know most my hindi from. i can understand hindi and speak a bit however i want to be able to at least speak hindi fluently. does anyone have any advice? im looking for something casual, not like a language course or lessons. maybe certain indian films or tv shows to watch? or anything else that can help really. Thanks!
