I got pretty excited when you asked about streaming 'The Lion's Den' because I just searched around last weekend trying to rewatch it. If you're looking to stream it right now, the safest bets are the big rental storefronts: Apple TV (iTunes), Google Play Movies, YouTube Movies, and Amazon Prime Video usually carry it to rent or buy. Prices jump around—expect $2.99–$5.99 for an SD rent and $9.99–$19.99 to buy HD, depending on the region.
If you're on a subscription hunt, sometimes 'The Lion's Den' pops up on Netflix or Hulu for limited windows, but that changes frequently. There are also free, ad-supported services like Tubi, Pluto TV, or
Plex that occasionally host older or indie titles; it's worth checking those if you don't want to rent. For library lovers, Hoopla or Kanopy can surprise you—if your public library participates, you might stream it at no extra cost.
For a quick, reliable lookup I use a service that aggregates availability across platforms so you don't waste time: it tells you whether it's included with a subscription, available to rent, or free with ads. Personally, I usually weigh price against how badly I want to rewatch—if it’s a comfort film for me, I’ll buy it; otherwise a cheap rent does the trick.
