It seems that the fantastic Showbox has been closed forever. Sad news I think we can all agree. As your entertainment guru I have found the good people of GC a couple of very decent alternatives. https://morphtv.net/catmouse-apk/#Install_CatMouse_APK_Terrarium_Clone_on_Android You can download this APK very easily from that link. It gives you access to all current movies and TV shows and also has a very good search facility that makes it easy to find your favs. I also downloaded HD Movie box from an app called APK pure. HD Movie box is almost identical to Catmouse. Both are clones of the excellent Terranium TV which was locked down last year. Enjoy.
Same, can find most things. I'm amazed that there are people out there "capping" things like 6:30pm local news from East Midlands. All good if you ever want to rewatch something though.
