These two films are not as widely known about as say.....'Arsenic and Old Lace', or 'North by North West', but they showcase Grant's skill/abilty to act two totally different types of character.
In the first film 'Mr Lucky', he plays the more recognisable slick and canny kind of character we expect him to play. A gambler/ganster/hustler who always has his eyes and ears open for the next quick money making scheme.
In 'None But The Lonely Heart', his role is not what we are used to seeing him perform. He plays an only happy-go-lucky son, of the local pawn shop widow woman. His habit of disappearing for for weeks/months at a time, is accepted by his 'Ma' and local residents as the norm. Things change though when life forces him to take a good look at himself.
I enjoyed both films as (especially the latter film) enabled me to see Mr Grant in a different light. That he did'nt alway play the slick dressed/sharp talking Hollywood leading man.
If you enjoyed 'Penny Serenade' - loved that film- then you may like this one. Yes. Grant can show emotion without blubbing. Typical man!
