Abstract: A new version of Komlós' theorem in infinite dimensions is presented. It gives a different approach to well-known theorems (C. Castaing [11], A. Ülger [30] and J. Diestel-W.M. Ruess-W. Schachermayer [17]).

Keywords: Bounded sequences in $L_X^1$; Biting lemma; uniform integrability; tightness; Komlós' theorem; weak compactness.
