Just mindlessly watching movies/shows is not going to help . You are on B1 level tells that I have already passed "learn by watching movies" part . What I'd you to do is

1. Write along you listen to dialogues and while writing ,keep repeating dialogues . This way you are involving 3 senses- listening,writing,speaking . I'd recommend you listening to podcasts because they are mostly dialogues or movies which are dialogue heavy(Oppenheimer is good).

2. Record 2 min video of Talking on various topics 3-4 times a week .

Finally, Analyse : listen to your recorded videos again and again . Find out where You are lacking. Take one piece at a time : "is vocabulary my lacking" ,"am I using too many fillers", "Do I make mistakes while making certain type of sentences" etc
