Pete (George Brent) gets married to concert pianist Sandra (Mary Astor) but their union isn't legal so he re-arranges another wedding date. However, Sandra already has commitments on that day which, quite rightly, she fulfils. I'm not sure why Pete has a problem with this but he does and off he goes to marry previous lover Maggie (Bette Davis) instead. The script then throws us by killing off Pete. However, Sandra has become pregnant by him and Maggie proposes a deal which becomes the Great Lie. Maggie will keep the child as her own while securing Sandra financially and no-one outside these two women should know anything of the deal. Well, guess what ?...Pete is not really dead and returns to Maggie where he assumes that she is the mother of his son. At this moment, Sandra appears back on the scene.....
The story is complete tosh. No way would a normal woman want to bring up a child that is not only not her own, but also belongs to her main love rival. It would be far more realistic to see her murder the baby. On the flip side, no way would a mother give up her baby to her main love rival - she'd abort or put it up for adoption rather than hand it to someone that she hates. The story of the Great Lie is ludicrous. But it doesn't matter coz it makes for great watching. And this is down to the two women Bette Davis and Mary Astor. Their sparring is very entertaining and continues throughout the whole film. Mary Astor takes the usual Bette Davis role and has great fun with the cutting one-liners. Her piano playing scenes at her concerts are a bit suspect but she manages to make what could be a very irritating bitchy character completely watchable and will have you thinking "oh good, she's back!" instead of "Oh no, not that annoying woman again".
The black cast at Maggie's home are completely annoying but they do sing a nice song on Pete and Maggie's wedding night. It's followed by a boy singing a crappy song but thankfully, they cut that one short. Despite the stupid storyline, the film is very watchable, especially whenever Davis and Astor have scenes together, and I anticipated a different ending - eg, Davis has no option but to kill Astor and thus preserve the Great Lie. Well, that's not what happens!
