Abstract: After a historical note on cosmological constant and its necessity for resolution of age crisis in the hot big bang model, I will briefly review the problems and prospects of scalar field models. I will then focus on the modified theories supported by chameleon/symmetron and Vainshtein mechanism and discuss their scope for late time cosmic acceleration. Finally, I will briefly touch upon some extensions of massive gravity.
