Yes, those two titles are the same. Ten Little Indians aka And Then There Were None and Murder on the Orient Express are both great movies but the twist in this movie was new to me and I'd not seen such a thing in those movies.

The idea of those people getting killed one by one by room keys being in their side when found dead might have been the same as the first movie. The fact that they were all connected is like Murder on the Orient Express. The rest was pretty new to me.
