On Marlene Dietrich and Jean Arthur Almost Throwing Down In the 1948 Movie, "Foreign Correspondent"

 

   Damn those horseshoes and hand-grenades. They ruin it every time. 

   As to who would have won, I see Dietrich coming out strong (possibly even dropping Jean a time or two), tiring considerably in the later rounds, and then Arthur ultimately winning via an 11th round TKO (Dietrich bleeding profusely out of both nostrils and unable to withstand the onslaught). Something like that.
