Since the discovery of molecular resonances in $^{12}$C+$^{12}$C in the early
sixties a great deal of research work has been undertaken to study
$alpha$-clustering and resonant effects of the fusion process at sub-Coulomb
barrier energies. The astrophysical $S^{*}$ factors of $^{12}$C+$^{12}$C fusion
have been extracted from several recent direct fusion measurements at deep
subbarrier energies near the Gamov window. They were also obtained by the
indirect Trojan horse method (THM). A critical comparison of recent direct
measurements and the THM, which elucidates problems in the analysis of the THM,
is proposed in this Letter to the Editor.
